Question

Q. (a) Draw a ray diagram to show the refraction of light through a glass slab and mark angle of refraction and the lateral shift suffered by the ray of light while passing through the slab.

(b) If the refractive index of glass for light going from air to glass is 3/2 ,find the refractive index of air for light going from glass to air.

Answer 1

hi ,


it's Ranjan Kumar



here is your answer !!!

hope it helps you dear friend !!!!



thanks !!!

b ) REFRACTIVE INDEX =>

wave length of light in air / refractive index of medium .


=> 3/2 = 1/ refractive index of air




refractive index => 2/3


=> 0.66



hope it helps you dear friend!!!

thanks
