Question

For the same angle of incidence in media A,B,and c the angle of refraction are 20,30 and 40 respectively.in which medium will the velocity of light be maximum?give reason of your answer

Answer 1

HEY MATE!

HERE IS YOUR ANSWER:

By snell's law we know that ,

angle of incidence / angle of refraction=refractive index

alo, speed of light/ speed in second medium=refractive index

so, angle of incidence/ angle of refraction= speed of light/ speed in second medium

Now, we are given that angle of incidence is same and speed of light is same.

now, 1/angle of refraction =1/ speed in second medium

so, angle of incidence is proportional to speed in second medium

Thus , third medium i.e C will have maximim velocity of light.

Hope it helped ^_^
