A ray of light is incident at an angle of

{60^0}

on one face of a prism of angle

{30^0}

. The ray emerging out of the prism makes an angle of

{30^0}

with the incident ray. The emergent ray is

View answer and explanation

Correct option: A

Normal to the face through which it emerges

Option A (Normal to the face through which it emerges) is correct because the angle of the prism is 30 degrees, and the deviation is also 30 degrees, implying the ray emerges normally.

\mathrm{\mu }

is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is Statement-A: The minimum distance between an object and its real image formed by a convex lens is

.

Statement-B: The distance between an object and its real image is minimum when its magnification is -1. Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances.
Reason: The focal length of a convex mirror is always taken negative. If both the object and image are at infinite distance from a refracting telescope its magnifying power will be equal to
