@Jabari Anson stop poisoning comment sections with this scam. Couldn't even bother to make it look realistic even compared to other similar scams.
You uploaded this video six years ago and yet it still saves lives! THANK YOU SO MUCH 😢
it's okay by me. Organic tutor is such a genius to have known almost all of the STEM courses and had been a real help to many of us.. a slight mistake like this one shouldn't count guys. Thanks JG for being a wonderful tutor to us all.. I pray God increases your knowledge to keep helping people the most. one love bro.

Shaun Zulu I was just about to comment the same thing. Crest is on top. Trough is on the bottom.
If you're exam is in just a few hours like me , you can definitely watch this video at 1.5 speed ! It's clear

Great Class for Beginners ❤️. His explanation was so good. Thank you so much.
You did mix up a few things but I was able to understand it after a few times listening. Good job and thank you.

crest and trough, he switched them somehow
WONDERFUL JOB!! I LEARNED SO MUCH !! THANK YOU!!!
dude dedicated talking to a computer for an hour for students like us.. Even though he has no relations with us... Great job.
No tutor in the whole world 🌎 🌍 comes close You’re the best by kilometers
Dude, you're a miracle worker! Thanks for such an amazing video!!!
Hey, bro the Crest is the highest part of the wave and the trough is the lowest☺
Literally the only chemistry and physics tutor I understand fr , thank you so much
don't be fooled by the sloppy graph...this guy is good!

But, my guy, the examples of light he gave had a wavelength of roughly 56x the circumference of Earth.
Thank you very much this video was very helpful and improved my understanding on most of this stuff.👍😁
I'm here having a mental breakdown because none of these were taught by my teacher but gave us a long quiz.
Thank you .This vid has truly helped me understand the equations better.
You're such a hero. I am so grateful for your work.
This really helped, Thanks!!
i owe you man...thank you so much...now im ready for tomorrow's test
Your just from delivering me a new brain ,now I am sure for the physics test . thanks for your service Amazon be proud of you now you have change my life.its time for me to show my mates what I know and do not have any stress for the mistake you did we all do thanks again
Thanks man, you helped me alot through this 1st and 2nd semester. Very very well.
I measured the voltage drop to light several led`s of approximately the same size using the diode mode of my Bryman multi-meter. The red one used the least amount of energy to light and was the brightest, but the yellow one used the most. The green one was in the middle.
I love how you always save me ! Thank you so much 💓
whole world is going to achieve 100% because of his teaching ngl
Love your Chanel! When I have the budget, I will definitely join! thank you
Your explanation survive me! I’m not clever at physics but you make me ! Thanks a lot
I was actually struggling with this but you make it seem easy and now I see it is ,thanks a tone bro ,god bless
I have around 3500 data points that create a wave. My task is to detect the maximum range of the wavelenght, so basically the largest distance from the crest to the trough and since my wave is pretty irregular I was wondering if there is a method to calculate and detect it. Take into account that between the crest and the trough there are also points (values) that I would of course exclude since they are not my crest nor my trough point.
U are very amazing tutor and l always much appreciating you , without u, we would be nothing at school
this guy is amazing ... thanks bro !
So thankful for you! You make my mind retain better 😊
Great video👍, highly informative and taught in an easy to learn, simple way.
This helps a lot, the explanation is very well said thank you!❤️😊
thanks a lot so useful videos,keep it up and try to cover many chemistry portions as yu can the teachers may also learn from your video🤩🤩🤓
Best teacher ever
bro has saves so many lives
Bestest explanation ever...lots of love from India 🙏
You are so helpful. Thank you so much for taking the time to make these videos.
Thanks, this really helped me. I just subscribed too. 😀
It clears all my concepts thank you so much, Pls make more videos .i have subscribed your channel
The crest should be at the top where the 5 is because the crest is the highest point the medium rises to and the trough should be at -5 because that is the lowest point the medium drops to so you made a small error there at 0:50 in the video but otherwise you provided a good explanation! 👍😀
Physics has always been a problem for me🤧 thanks for thissss
awesome! best teacher ever I love physics because of you …

Nice explanation and I like your examples. Just recheck your concept of Crest and trough.
Do you have videos on snapshot graphs and history graphs or periodic waves and their displacement moving right and left ? Thanks
Thank you sir. This was lit!
Thanks really i appreciate your effort ♥️
Yoh 🥺 You have been so helpful 😢thank you kinda sir for making this simple and straight forward.
Bro you are amazing dude ...thanks alot!!
thx for this, got a physics exam tmr, ur amazing
Thanks I've learned a lot.
Amazing tutor ever!🥳
Perfect I have enjoyed and understood
Excellent. Thanks.
Quantum Mechanics is so ✅ and this is the prelude to it
Amplitude above x-value = 0 is a crest. Amplitude below x-value = 0 is a trough.
Great explanation!
You're the best teacher ever😇 God will bless you and increase your knowledge 🙏🙏
Saved my life, thank you
13:30 you can also count the number of oscillations (cycles) divided by the time . Like there is 1¾ cycles in the wave to 14 seconds.what about one cycles 1¾->14s 1 1x14 ÷7/4 14×4 =56 56÷7 = 8
Man is a goat. I learned more from this guy than from my teachers.
your videos are amazing, you explain very very well, thank to you is easier to learn physics :)
you are a life saver ! pls know that
When tmmrw is exam, this guy know the bestt!!
Am doing well in physics because of you... Thanks much ❤🙏
Awesome....thanks.
Awesome video & interesting bro
Best explanation ever
would it be possible if u are able to make a video on nodes, anti node(stationary waves), diffraction of waves ,single and double slits, as well as diffraction grating
thankyou so much you are awsome!
Still confused but i learn more things about this video and thank you
Excellent 👌 job
Thank you once again.
"Wave stuff"
Clear explanation Thank you❤
Thank you so much
at 67 your enlightening me to Physic and I'm thankful
Good and super brother😮🎉❤😂😊
Thank you very much teacher
best teacher
Thank you so much!!!
thank you so much😘
thank you for your videos
Thanks it kind of helped me
Man I've had 3 months for Understanding this And I couldn't. But Now ( oh yeah bebe)
My Bro got a bit confused there with the Crest and Trough
Good job Thanks
Well for a transverse progressive wave, the crest supposes to be at the top of the trough.
6:35This is the definition of the time period since wavelength is the spatial period of a wave.
Thanks buddy
This guy is too good
