A light ray from an object 'P' is reflected from a mirror as shown in the figure, then

Interference effects are produced at point P on a screen as a result of direct rays from a 500 nm source and reflected rays from a mirror, as shown in figure. If the sources is 100m to the left of the screen and 1.00 cm above the mirror, find the distance y (in milimeters) to the first dark band above the mirror.

Sun rays are reflected from a horizontal mirror and fall on a vertical screen. A vertical object of height h is placed on the mirror as shown in the figure.Length of the shadow on the screen is

A light ray is incident on a plane mirror, which after getting reflected strikers another plane mirror, as shwon in figure. The angle between the two mirrors is 60^(@) . Find the angle 'theta' shown in figure.
