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
