Asok Kumar Das and Chittaranjan Dasgupta Solutions for Chapter: Reflection of Light, Exercise 1: EXERCISE 12

The radius of curvature of concave mirror is $24 \mathrm{cm}$ and the image is magnified by $1.5$ times. The object distance from mirror is

Statement $1$. The formula connecting $u, v,\text{ and} f$ for a spherical mirror is valid only for mirrors whose size is very small compared to their radii of curvature. Statement $2$. Laws of reflection are strictly valid for a plane surface, but not for a large spherical surface.

A ray of light is incident at $50°$ on the middle of one of two mirrors arranged at an angle of $60°$ between them. The ray then touches the second mirror, gets reflected back to the first mirror, making an angle of incidence

The magnification of the image when an object is placed at a distance x from the principal focus of a concave mirror of focal length f is given by?

Two plane mirror are perpendicular to each other. A ray after suffering reflection from the two mirrors will be

An infinitely long rod lies along the axis of the concave mirror of focal length f. The near end of the rod is at a distance x > f from the mirror. Then the length of the image of the rod is

Two plane mirror A and B are aligned parallel to each other, as shown in Fig. A light ray is incident at an angle $30°$ at a point just inside one end of A. The plane of incidence coincides with the plane of the figure. The distance between two mirrors is $0.2m$. The maximum number of times the ray undergoes reflections (including the first one) before it emerges out is?

A short linear object of length b lies along the axis of a concave mirror of focal length f at a distance u from the pole of the mirror. The size of the image is approximately equal to
