- 120 - Refraction of Light
In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to calculate the angle of refraction. When the angle of incidence exceeds the critical angle it will result in total internal reflection.

That's a point I am looking for . Finally i have able to understood why bending of light related to the speed.
Every school should show this.
thank you i learned more in 10 minutes than in a month of class
i literally learnt more things in 11 min than 6 hours in class lmao
Thank you so much! I had to read the chapter and come back to this video several times to understand what exactly your illustrating when light-slows-down when it goes towards a denser medium (grass) and how light-speeds-up when it goes from a denser medium to a less dense medium (air)
the moving band analogy is great but i would have appreciate a lot if there was an explanation why light is working this way. one photon is one, he is alone, not four marching side by side.
You're amazing! I appreciate your videos so much, not sure how I would've gotten through school without you!!
The best explanation I ever got about refraction. Thanks a lot!
Your videos make things clearer.thanks!☺
Amazing video, it really helped me remember al the stuff I learnt from highschool! Really great and on point examples, thanks!
Yes! You just saved me one day of studying! Like Chen said; learnt more in 11 min than in 6 hours of class!
This way of theaching is amazing, it should be a global standar!! Thanks for this videos Paul!!
this is the best video i saw till now about light and how it behaves thank you
Thank you so much! This was so understandable!
I love the analogies! Helped me a lot! Thanks!
hi sir...... i want to thank you because your lessons helped me a lot......you also give quality of content and i hope your channel rises.....i wish you would have been my science teacher ;) (i live in india)
Thank you for this video! :D Really liked the marching band metaphore. It made everything easier to understand
it is extremely helpful.Thanks so much
one of the best lectures in optics.
Best explanation I've ever seen.
