Question

a) The critical angle for certain wave length of light in case of a piece of glass is 30º and the amplitude of the light is 5cm. Calculate i. The polarization angle of glass ; ii. The angle of refraction ; iii. The refractive index of the medium ; iv. Initial intensity of the light ; and v. Final intensity of the light.

Answer 1

Explanation:

When light encounters a boundary between two media with different refractive indices, some of it is usually reflected as shown in the figure above. The fraction that is reflected is described by the Fresnel equations, and is dependent upon the incoming light's polarization and angle of incidence.
