For light incident from air onto a slab of refractive index 2. Maximum possible angle of refraction is,

Glass has refractive index mu with respect to air and the critical angle for a ray of light going from glass to air is theta . If a ray of light is incident from air on the glass with angle of incidence theta , the corresponding angle of refraction is

A ray of light is incident on a glass slab of refractive index 1.5, making an angle of 40^(@) with the surface. The angle of refraction in glass is

A ray of light is incident at an angle I on a glass slab of refractive index mu . The angle between reflected and refracted light is 90^(@) . Then the relationship between I and mu is
