My GE microwave from 2005 finally crapped out. At first kzread.infoUgkxO_Bc204MGjxDl87cOKcdgaRhzSqGmv_g I was unsure because I was looking for something with the exact same features. Found it with this one. Interior space cavity was large, but the outside was smaller than my old one. I love the one-button push for 1-6 minutes, and the 30 second add or 30 second start. and MOST IMPORTANTLY, I love how you can adjust the power level during cooking. The reviews said it could not be done, but this marked all the other boxes. and happy to say, it does. I can hit 1 minute start, and change the power level from 10 to 5, 30 seconds in, without interruption. my favorite feature!

This video explains exactly why I prefer my older microwave. Instead of a rotating plate and a stationary waveguide on the side, mine has a stationary plate and a spinning waveguide above the food chamber, spun by air from the exhaust fan. It distributes microwaves more evenly. Much simpler and far more efficient, and less parts that can break or wear out.

Things I learned from this that no even talked about in school or even university/college: Reflected waves is 180° flip along Y axis of the wave that would have propagated if there was no reflector. Heating using microwave is caused my friction due to oscillating water molecules. The L=N*wavelength/2, it's application. The standing wave application in a more easy to understand way. And lastly it was in a fun and thought provoking manner.

My older microwave malfunctioned once and didn't turn off when I opened the door. My hand closest the microwave felt like the hair was standing up. Didn't hurt or anything. I turned it off after a couple seconds I realized what was happening. Years later they had to cut off my hand due to massive deformities. Kidding.. nothing happened.

The cooking from the inside part just isn't true. The strength of the wave inside the food is of function e^-x and the more inside you are the weaker it is. The inside gets heated by the little wave strength that is there and by the heat passing from the outside to the inside. Put anything relatively large in the microwave and cut it in half after heating it. You will see that its colder on the inside. That statement really killed the video for me...

There are some exceptions. For example a jam filled doughnut. In fact, because of the lack of H2O in the dried out bread and the abundance of H2O in the jam center, all the microwave energy goes towards heating the jam. It is in fact quite dangerously deceptive, as you'd take out the jam doughnut and it will feel a little warm, but as you bite into it you'll get a nasty surprise because the center will be extremely hot. Also, as cardboard and plastic do not contain any H2O there is no effect of heating resonance from their molecular structures. This is easily demonstrated by heating pizza in a microwave while still in its cardboard box takeaway container. The cardboard is not hot, yet the pizza is.

Amazing! So, i could learn that a standing wave is concerned by 2 microwaves interfering on each other. A first microwave (incident) is created from an electric source and flows through the resonance cavity. When it finds a reflector, the first microwave reflects and creates a secondary microwave in opposite way. The phase of the secondary microwave is 180 degrees distant from the first one. Implies that at this moment one phase is canceling the other when the amplitude is maximum and minimum, one to the top and other to the bottom. But as the 2 waves is travelling, the distance between the phases isn't static, so when the 2 microwaves encounter at the moment of maximum amplitude for both of them, they interfere constructively, point of maximum energy. That's the reason that the standing microwave formed is applying more energy always at same points, cause the distance between phases is varying, but as it's originated of the same source, they have the same frequency, velocity and amplitude, the points of maximum amplitude of both of them will always be the same. Interesting that the encounter of no amplitude of them, don't create more energy at all. But as microwaves flows, that's the point that they encounter constructively. It was not common sense to me. Thanks!

However, your answer could also be interpreted for the case where there is a fan rotating in the ceiling of the MW oven (randomly?) distributing / reflecting microwaves within the oven while the food is stationary. But also this can be argued against because if you look closely the model has the design where food is rotating (rotating mechanism at the bottom). So, if I am correct in my chain of arguments, then the food (cheese) is stationary, the generated microwaves must also be stationary (no reflecting fan in the ceiling).

Its kind of a pity from a didactics and educational point of view: In the 5 - 10 minutes before operating the microoven you imprinted a picture of a standing wave in the head of students, but then the hotspots are not where they are expected according to the standing wave picture......

Since metal basically reflects the waves back, the inside of a microwave is built out of metal which doesn't let the waves pass through (as they reflect back in), same with the glass that most probably contains a thin layer of metal which does the same job. And so the waves never go outside of the microwave oven but remain inside throughout the duration. That is the reason why, when opening the door to the microwave oven while it is working shuts it off, it's a safety feature as to not allow the waves to go out of the microwave since the door isn't there to reflect it back anymore

Video: "Cook from the inside out" Me: True, you can boil water even if it is inside a covered small ceramic container. And the ceramic wont became that hot, only the water will start to boil. But for a large chicken you need to adjust the wavelength a bit so it penetrates deeper and add a couple of watts to cook a whole chicken, but then you have it. Did not hear that detail in the commercial :-)

And, of course, if you're teaching the kids about electromagnetic waves you can use a large slab of chocolate as shown to get the hotspots (disable the turntable first). Then measure their spacing and with a bit of detective work on the frequency and very simple maths they can calculate both the wavelength and the speed of light. If successful, they get to eat the experiment. Might have to do it more than once to get a spread of clear results to average (!)

Great video! Maybe you could explain in another one the Faraday cage used to trap the microwaves.

There were way too many inaccuracies in this video. The most glaring one was cooking from the inside out. While it is true microwaves penetrate food, they are attenuated fairly rapidly and so do not make it to the very center of a mass of food item with any appreciable volume. Microwave ovens still rely on conduction to transfer heat from more outer regions of the food to more interior regions. That’s why the defrost program typically cycles the magnetron on and off. (Inverter based microwaves excepted which turn the power down thus allowing time to conduct heat to the interior in a similar fashion)

Never mind the melting chocolate bar in the scientist's hand, he should probably stop playing with microwaves and go directly to the emergency room based on what looks like 3rd degree burns!

it´s a chocolate bar... not an metal bar... no need to have such amount of energy (heat) to melt down

Brilliant explanation 👍👍👍

Excellent!

I don't understand how it can be concluded that a microwave cooks from inside-out. When the micro-wave comes in contact with the food, some energy first gets absorbed at the surface before going inside the food. So, a better conclusion would be that the food gets cooked evenly from inside and outside. Please correct me if I am wrong.

Maybe it is due to the water content because when you keep for outside the surface molecules evaporate first but the innermost molecules almost do not evaporate. More water = more thermal energy absorbed, therefore I guess it depends on the water content inside the food.

@@aumpauskar4653 Nicely explained. But if the food is layered such that the outer part has lot of water than the inner part, the food does get cooked from outside. So I guess it is more appropriate to say that the food gets cooked evenly, both inner and outer part recieves heat.

@@longbow6416 Because of the difference in water content within different parts of the Hot Pocket. The filling inside has much more water in it than the bread on the outside. Even pieces of meat within the filling are going to heat differently than the liquid part.

helps a lot thanks

Thank you!

I worked over 25 years in restaurants industry . I have seen so many people place food inside microwaves for 5 minutes then not even one minute passes by they don't even wait for it to stop and they rip the door open exposing everybody to microwaves . That is how microwaves are dangerous . BUT if you wait for it to finish or switch it off then open the door it's perfectly safe.

Microwaves are not energetic enough to cause permanent damage. They will at best give you a burn (and even that only if you hold you hand inside for extended times; ie cook it) nothing more.

Fantastic video 😊👍 The animation made it more easier to understand such a complex working of microwave.

learnt something new today

Huge information superb

6:25 - Finally someone explained in detail how exactly a food microwave works. So the greatest peaks of the microwave’s amplitude is the one that creates hotspots? It would make sense since all peaks in a wave has the most energy. What would happen if the peak of the microwave is below the food? As if the peak of the wave is actually greatest at the surface of the microwave oven’s floor and not on the surface of the food? Maybe the microwave oven is designed such that the peaks of the wave will always remain at the level of the surface of the food…

the standing wave pattern of a 1D system is simple, the standing wave pattern of a 2D system is a mess, the standing wave pattern of a 3D system is hell, it is next to impossible to "design" the cavity in any meaningful sense other than just make it and ok if there's no fatal flaw.

One important thing to mention.. Never ever put a metal in a microwave oven. (my 6yrs old son asked me to write it)

Explanation 🧡👌🏻👌🏻🙌🏻

Excellent explanation 👍

Litton microwave had a solution that bounced the waves around using a fan essentially to make the waves hit most of the cavity… they were also working on the shorter waves to sear meats. Then cook with the longer waves. They had some really cool stuff. My dad has cooked a brown and juicy turkey in his older Litton microwave.
