If the angle of incidence and angle of emergence of a light ray falling on a glass slab are i and e respectively, then prove that i=e.

When light ray passes form air to glass slab then it____.

A ray of light passes through an equilateral glass prism in such a manner that the angle of incidence is equal to the angle of emergence and each of these angles is equal to 3/4 of the angle of the prism. The angle of deviation is

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

One student is doing experiment to draw the path of light rays passing through a glass. For this, he measured the angle of refraction and angle of emergence for every angle of incidence. In all the cases he found that

An parallel beam of monochromatic light is incident on a glass slab at an angle of incidence 60^@ . Find the ratio of the width of the beam in glass to that in air, if the refractive index of glass is 1.5.

A ray of light is incident on the surface of a glass plate of thickness t . If the angle of incidence theta is small, the emerging ray would be displaced side ways by an amount (Take n = refractive index of glass)

A ray is incident at an angle of incidence i on one surface of a small angle prism (with angle of prism A) and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , then the angle of incidence is nearly equal to:

When a light ray makes an angle of 90^(@) with surface of glass while entering a glass slab from air, it

A ray is ihncident at an angle of incidence ii on one surface of a prism of small angle A and emerge normally from opposite surface. If the refractive index of the material of prism is mu. the angel of incidance I is nearly equal to

For a glass prism (n = 1.5), having refracting angle 60^@ . Determine the range of the angle of incidence, for which emergent ray is possible from the opposite surface and the corresponding angles of emergence. Also calculate the angle of incidence for which i = e. How much is the corresponding angle of minimum deviation?
