A ray of light travelling through rarer medium is incident at very small angle i on a glass slab and after refraction its velocity is reduced by 20%. The angle of deviation

Light is incident at an angle i on a glass slab. If the reflected ray is completely polarised , then the angle of refraction is

Light is incident at an angle i on a glass slab. The reflected ray is completely polarished . The angle of refraction is

Light is incident at an angle i on a glass slab. The reflected ray is completely polarished . The angle of refraction is

A ray of light travelling through a denser medium is incident at an angle I in a rarer medium. If the angle between the reflected ray and refracted ray is 90^(@) , show that the critical angle of the two media, theta_(c) = sin^(-1) (tan i)

A ray of light is incident normally on a plane glass slab. What will be (i) the angle of refraction, and (ii) the angle of deviation for the ray ?

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

A ray of light travelling in air is incident on the surface of glass slab at an angle of 40^(@) . If the ray is deviated through 18^(@) , determine critical angle for the glass-air interface.
