Question

for the same angle of incidence in media ABC Bank of refraction at 20 degree 30 degree and 40 degree respectively in which medium velocity of light be maximum give reason in support of your answer​

Answer 1

Ello user !!!!!!!!

Here is your answer,

==============================================

As sini/sinr = u

More the r more the sinr therefore lesser will be refractive index

As refractive index is inversely proportional to speed in medium

therefore lesser the refractive index more the speed

Therefore 40 degree will have maximum speed

===============================================

HOPE THIS HELPS YOUU :)

AND STAY BLESSED.
