Indicate incident ray, refracted ray and normal at the point of incidence using a ray diagram.

What is incident ray and reflected ray?

A ray of light is reflected by a plane mirror. hatepsilon_(0), hate and hatn be the unit vectors along the incident ray, reflected ray and the normal to the reflecting surface respectively. Which of the following gives an expression for hate ?

A ray of light is incident on a prism of refractive index mu and angle A at the angle of incidence i_(1) and emerges at the angle i_(2) . If the ray is incident on the prism at the angle i_(2) , calculate the deviation of the ray.

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.

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?

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?

A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is 30^(@) . Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? [sin 48^(@) = 0.75]

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