Refraction of Light
This physics video tutorial provides a basic introduction into the refraction of light. It discusses the law of reflection and the law of refraction which is also known as Snell's Law. The law of reflection states that the angle of incidence equals the angle of reflection. This video also explains how to calculate the angle of refraction as well as the critical angle that leads to total internal reflection. This video also explains how to calculate the speed of light in water. The speed of light decreases as light moves from a material with a low index of refraction to a material with a higher index of refraction.

Thank God you exist, I have a physics exam tomorrow which is really important and is 90% of my grade and i bearly understood this in the lesson, Thanks
Dude you're so f**king smart it's unreal! You're honestly a true gem and must be protected at all cost! Thank you for everything and I want you to keep making videos!

Me too. Was just explaining this to my daughter, who was noticing how the appearance of her straw changed when put in a glass of water. Thought, I need to review that formula...what was it? Oh yeah, Snell's Law.
Great explanation; terse yet very easy to understand.
You are great mate just loved the explanation. Thank you
Very explanatory video! Thanks so much.
Finally got the point I wanted. Thanks a lot!
You just saved my mid-year exams, thank you so much!

Thank for your videos, just one correction 1:17-1:23 The law of reflection states the angle of incidence is equal to the angle of REFLECTION not refraction. Again love all your videos!

best teacher ever ily
Sir please make a video on how to write decomposition reactions including polyatomic ion other than binary coumpounds
I wish I found this video when I took physics in college. Physics 2: electricity and magnetism was the hardest course I’ve ever took. And I took higher level math course such as real analysis, statistics, number theory, etc. nothing was as hard or as bad as physics 2.
Thanks for this... ✅
We just started this today in class what a coincidence!
Yup, you win.
Thanks alot sir,,this was so helpful...bravo

Everything, whether on social media or consciously looking at somebody in person is controlled by your own mirror image until certain gene signal’ occurs that allows memory to dissolve and new neuroplasticity to occur.

Good thing I know this. I took physics in 10th grade but the light refraction chapter, we didn’t get to that yet, so I’m glad I got to see this since I never took it. Flat earthers need this. I’m not a flat earther. No evidence of it.
Light travels the same speed regardless of the material “it” travels through. What you are measuring is the resultant wave of multiple waves interfering with one another. Light is not a particle. It is a spherical wave front that hits electrons in a reflective material at different times. When that sphere first hits the surface, those first electrons begin to vibrate at the same frequency as that light. Vibrating charges create new wavefronts. As the original wavefronts continues on, more and more electrons begin to vibrate and they all create their own wave fronts. Where they constructively interfere, you get the reflected light. That’s also why reflected light is polarized parallel to the surface of reflection. Those valence electrons are in the conductive band which limits their vibrations along the plane of the material surface. When a light “refracts,” it is passing between the molecules in a transparent material. This has the effect of a diffraction grating causing more and more spherical wavefronts to interfere with each other which the “refracted” ray being the resultant wave appearing at a different angle than the incident “ray.” Just wanted to toss that out there if anybody is interested in quantum mechanics and would rather not have to unlearn a basic approximate explanation. Good video, though.

Thanks I wanted to know about this
so the angle with the normal and the reflected angle is called the angle of refraction, and the angle with the normal and the refracted ray is also called the angle of refraction? Are we sure thats right?
Really helped.
good video tutorials, cant download anything for offline use. help

THANK YOU!
Thanks alot😊
thank you so much
1:15 - I'm brand new to this so I'm trying to get the terms right. I assume you meant to say, "the angle of incidence is the same as the angle of REFLECTION," correct? Not nit-picking...I'm just learning this from scratch so I've got to make sure I understand. Thanks!

Got a death ray idea for design but I need to learn the maths definitions 😂
Thank you
Your angles are all over the place.. can you make another version where you don’t skip between quadrants?
1:23 You accidentally said the angle of incidence is equal to the angle of refraction here. It is not, the angle of incidence is equal to the angle of REFLECTION.
Thanks alot
