Laws of Refraction of Light | Don't Memorise

[@InfinityLearn_NEET]

#DidYouKnow: Light in swimming pool refracts and gives it a shallower look when the straight light strikes it at the bottom and bends at again the water surface causing refraction of light. ✅To access all videos related to Reflection and Refraction, enroll in our full course now: infinitylearn.com/cbse-fullcourse?KZbin&DME& To watch more Physics videos, click here: bit.ly/PhysicsVideos_DMYT

is red light traveling slower then the speed of light comparing the speed of light for purple light

I think the best ever videos I have seen are of don't memorise. whenever Ihave any kind of doubt related to science, I always see a video from don't memorise and the doubt gets crystal clear. refraction of light is a thing in which i always get confused, but now after seeing the video, I need not see any video. I love don't memorise.

[@bug7756]

Whenever I search a topic on KZbin and see that you have uploaded a video on it I click on it faster than than the speed of light 😂

Just in love with the way of teaching😊, I understood the concepts very well. Thank you so much mam:-)

[@jimbrannan6757]

The most interesting thing I remember in school was when they showed us the light reflection properties of the bevel on a mirror. It was amazing the angle it traveled. You looked straight at a 45 degree angle bevel to the right and you saw to the left instead of right like you would think. I remember they demonstrated it with showing light travel entering the glass as two wheels. The light would bounce off the glass just like a car on two wheels hitting a flat surface. It was Amazing. Here I am searching for a video on it and everyone covers all the boring stuff.

This video helped me understand refraction and its laws perfectly. There is another concept, total internal reflection, which seems a little difficult. If your channel can make a video explaining that, it would be really helpful to me as well as other students out there.

Don't memorise is one of my most favourite learning channel but this video has no examples with real life, so I can't understand this consept. But other videos which has examples comparing to real life is more understandable.

Simplify the fraction. It should equal v1/v2.
