Demostrate that a light beam reflected from three mutually perpendicular plane mirrors in succession reverses its direction.

A ray of light is reflected by two perpendicular plane mirrors as shown. The angle theta is equal to:

In a plane polarised light, name three parameters which are mutually perpendicular.

When the light is reflected from the surface of the mirror, its speed and wavelength will

A light ray incident on a plane mirror gets reflected from it. Another plane mirror is placed such that the reflected ray from the first mirror is incident on it If the reflected ray from the second mirror travels perpendicular to the indecent ray on the first mirror, determine the angle between two plane mirrors.

A light ray gets reflected from a pair of mutually _|_ mirrors, not necessarily along axes. The intersection point of mirrors is at origin. The incident light ray is along y= x+2 . If the light ray strikes both mirrors in succession, then it may get reflected finally along the line:

When light is reflected from a mirror a change occurs in its :
