Statement-A: Minimum deviation for a given prism does not depend on the refractive index

\mu

of the prism.

Statement-B: Deviation by a prism is given by

\delta=\left(i_1+i_2-A\right)

and does not have the term

\mu

View answer and explanation

Correct option: A

A and B are correct

Option A (A and B are correct) is correct because minimum deviation does depend on the refractive index, and the deviation formula doesn't explicitly show

\mu

but it's implicitly there.

An object 5 cm tall is placed

\mathrm{1}\,\,\mathrm{m}

from a concave spherical mirror which has a radius of curvature of

\mathrm{20}\,\,\,\mathrm{cm}

. The size of the image is Red colour is used for danger signals because A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If

\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

2{f}

.

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
