Question

(i) 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. (ii) 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

1st one is the answer for the 1st sub division of ur question

2nd image is the answer of the 2nd sub division of ur question

I hope this will help you

thank you

Answer 2

1. refractive index of glass from air = 3/2
2. refractive index of air from glass =1/ang => 1/ 3/2 = 2/3
