If the angle of incidence is equal to critical angle, then the angle of refraction is

In total internal reflection when the angle of incidence is equal to the critical angle for the pair of media in contant, what will be angle of refraction ?

.......... obtained at angle of incidence equal to critical angle is called critical ray.

A ray R_(1) is incident on the plane surface of the glass slab (kept in air) of refractive index sqrt(2) at angle of incident equal to the critical angle for this air glass system. The refracted ray R_(2) undergoes partial reflection & refraction at the other surface. The angle between the reflected ray R_(3) and the refracted ray R_(4) at that surface is :

For a prism of refractive index 1.732, the angle of minimum deviation is equal to the angle of prism. Then the angle of the prism is

Find the lateral shift of a light ray while it passws through a parallel glass slab of thickness 10 cm places in air. The angle of incidence in air is 60^(@) and the angle of refraction in glass is 45^(@) .

For a glass prism (mu = sqrt(3)) , the angle of minimum deviation is equal to the angle of the prism . Find the angle of the prism .

A ray of light passes through an equilateral prism (refractive index 1.5 ) such that angle of incidence is equal to angle of emergence and the latter is equal to 3//4 th of the angle of prism. Calculate the angle of deviation.

A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster's angle phi . If mu represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is

A ray of light travelling in water is incident on its surface open to air. The angle of incidence is theta , which is less than the critical angle. Then there will be

If the angle of a prism is 60° and angle of minimum deviation is 40°, then the angle of refraction will be ....
