Vishal wrote the word 'LIGHT' on a paper and placed it in front of a plane mirror (as shown in the figure) and noticed how the letters of the word appear in the mirror. Write down what he noticed in the mirror

 

Two identical mirrors are placed in a hollow cylindrical tube as shown in the figure. A light ray incident on one of the mirrors undergoes multiple reflections. If the length of each mirror is $3 \mathrm{m}$, and the velocity of light is $3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$,  then find the time taken by the light ray incident on the mirror to come out of the hollow cylinder.

In the figure, $AB$ is an object and $A^1{B}^1$ is the image formed when a spherical mirror is placed at point$P$ . Identify the type of mirror and describe the nature of the image. (Where $F$ and $C$ are focus and centre of curvature of the mirror).

A laser source placed between two concave mirrors sends light rays as shown in the figure. If $PQ$ and $RS$ are parallel to the principal axis, determine the focal lengths and radius of curvatures of both the mirrors.
