Q12 of 284 Page 228

The speed of light in vacuum and in two different glasses is given in the table below:


(a) Calculate the absolute refractive indexes of flint glass and crown glass.


(b) Calculate the relative refractive index for light going from crown glass to flint glass.

The relation between the angle of incidence and the angle of refraction for a medium is


Refractive indexes of flint glass = 1.61



Refractive indexes of crown glass = 1.52



The relative refractive index for light going from crown glass to flint glass = 1.059

Define Snell's law of refraction. A ray of light is incident on a glass slab at an angle of incidence of 60°. If the angle of refraction be 32.7°, calculate the refractive index of glass. (Given: sin 60° = 0.866 and sin 30° = 0.5).
