Refraction of a light through a prism. step Wise. ncert 10 activity 11.1

Answer 1

Hello there...

Here is what I got for you...

Your question is..

Refraction of a light through a prism?

Here is what I know..

R is the angle of refraction. The refractive index of many materials varies with the wavelength of the light used. This phenomenon is called dispersion. This causes light of different colors to be refracted differently and to leave the prism at different angles, creating an effect similar to a rainbow.

Hope this helps!!!

If i'm wrong let me know...

Have a good day...

Answer 2

✔The change in direction or bending of a light wave passing from one transparent medium to another caused by the change in wave’s speed is the refraction.

✔When the ray light enters the glass, it bends towards normal and when ray comes out, it bends away from the normal. Now the angle between the emergent ray and incident ray is the angle of deviation.
