A prism having an apex angle `4^(@)` and refractive index 1.5 is located in front of a vertical plane mirror as shown in figure. Through what total angle is the ray is deviated after reflection from the mirror ?

A prism having an apex angle of 4^@ and refractive index of 1.50 is located in front of a vertical plane mirror as shown in the figure. A horizontal ray of light is incident on the prism. The total angle through which the ray is deviated is:

A right-angled prism of apex angle 4^(@) and refractive index 1.5 is located in front of a vertical plane mirror as shown in figure. A horizontal ray of light is falling on the prism. Find the total deviation produced in the light ray as it emerges 2nd time from the prism.

A prism having a refracting angle 4^(@) and refractive index 1.5 is located in front of a vertical plane mirror as shown. A horizontal ray of light is incident on the prism. What is the angle of incidence at the mirror ?

A small angled prism of apex angle A=4^@ and refractive index mu=1.5 is placed in front of a vertical plane mirror as shown in figure. If the mirror is rotated through an angle theta, then the light ray becomes horizontal either after the mirror or after second time passing from the prism in opposite direction. The value theta is

A horizontal ray of light passes through a prism of index 1.50 and apex angle 4^(@) and then strikes a vertical mirror , as shown in the figure. Through what angle must the mirror be rotated if after reflection the ray is to be horizontal?

A ray is incident at 30^(0) angle on plane mirror.What will be deviation after reflection from mirror ?

P is small angled prism of angle 3^(@) made of a material of refractive index 1.5 . A ray of light is incident normally to the mirror as shown in figure. M is a plane mirror. The angle of deviation for the ray reflected from the mirror M with respect to the incident ray is :

Figure shows a small angles prism angle 4^(@) and mu = (3)/(2) . A light ray almost normally incident on the prism is refracted and falls on a vertical mirror as shown. Find the total deviation of the ray after reflection from the mirror.

A mirror is turned through 15^(@) . Through what angle will the reflected ray turn ?
