Show that refracted rays leaves parallel to incidented ray white refracting through a glass slab.

The angle of deviation of a ray of light refracted through a parallel glass slab is

A ray of light strikes a glass plate at an angle of 60^(@) . If the reflected and refracted rays are perpendicular to each other, the refractive index of glass is

A ray of light incident on a medium at polarising angle.what will be the angle between the reflected and the refracted rays? Or, an unpolarised ray of light is incident on a rectangular glass block at Brewster's angle. What will be the angle between the reflected and the refracted rays?

What type of mirror is used by the dentists? Why a ray of light does not deviate as a result of refraction through a glass slab?

Monochromatic rays of light coming from vacuum are refracted in a medium of refractive index mu . Show that the ratio of the wavelength of the incident ray that of the refracted ray is equal to the refractive index of the medium.

Show that for refraction of light through a parallel glass slab, the incident ray and the emergent ray are parallel to each other. Or, With the help of a diagram show how in case of a rectangular glass slab, when light is refracted by the two parallel faces of the slab, deviation between angle of incidence and angle of refractive is zero.

A ray of light passing through the medium of refractive index mu_(1) is incident on the surface of separation of another medium of refractive index mu_(2) . A part of the ray is reflected and another part is refracted. What should be the angle of incident so that reflected ray and the refracted ray are at right angles to each other?

Calculate the angle of deviation of a light ray refracting through a equilateral prism angle of incidence and refraction are 40^@ and 30^@ .
