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

[milky.rev.]

Literally taught me in 10 minutes something my teacher has spent 4 weeks trying to teach. Tysm def subscribing

[momsspaghetti]

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!

[bbcclub]

This guy really said if my memory didn’t fail me. Bruh he remembered this from high school, that’s crazy.

[leopard]

You are the best teacher I have ever learned from 🕊 thank you

[hilchs]

You just saved my mid-year exams, thank you so much!

[etemkaandelibas]

I was just wondering the mathematical calculations. Thanks for the video.

[mmesomaobioha]

Thank you so much, you just saved me. I was literally crying while reading this topic. I very much understand 'em now. Thanks a whole lot

[aleciagreen]

Thank you so much for this video, it totally helped to improve my understanding of refraction

[AJ-ullt]

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!

[Eknoor-lA]

Thank u it helped a lot because I am a Science Olympiad student for optics and i was a bit confused so thank u.

[gyangjoshua-xf]

Very happy for that lecture, is one of the course to write exams this semester.May God reward you.

[ianellewachekwa]

You’re so underrated. You should be getting thousands ngl

[schifoso]

Great explanation; terse yet very easy to understand.

[AinaAndrew]

4 hours time I will do a test on this now, thank you, very much.

[asayilethindwa]

As you have always been improving my understanding msn

[KillerTacos]

This was explained so well, thank you!

[hoshyflix]

this helped me so much explained better than in school lol ty!

[Ay_aa_]

Wow, I don't know how I can thank you, you are really a great Thanks, thanks ❤❤❤

[anakienpezzotta]

This is gold. My only problem was finding an calculator with sin*-1. Thx
