A light ray hits the pole of a thin biconvex lens as shown in fig. The angle made by the emergent ray with the optic axis will be approximately

An equiconvex lens has its two surfaces of radius of curvature R = 10 cm . Thickness of the lens at its centre is 2 cm. A light ray is incident making an angle of 2° with the optic axis of the lens. Find the angle that the emergent ray will make with the optic axis. The refractive index of all media is as marked in the Figure.

Read the following statements and choose the correct option. (A) The angle made by the incident light ray with the plane of mirror is equal to the angle made by the reflected light ray with the plane of mirror. (B) The angle between an incident light ray and a reflected light ray is twice that of the angle between the incident light ray and normal.

A mirror is inclined at an angle of theta with the horizontal. If a ray light is incident at an angle theta as shown , then the angle made by reflected ray with the horizontal is

A mirror is inclined at an angle of theta with the horizontal. If a ray light is incident at an angle theta as shown , then the angle made by reflected ray with the horizontal is
