Why the convex and concave mirrors are called spherical mirrors?

What is meant by the pole of a spherical mirror?

What will be the angle of incidence when a ray of light passes through the centre of curvature of a concave mirror?

What is reflection of light? Write law of reflection and draw labelled diagram.

Correct relation between radius of curvature($R$) and Focal length ($F$) of a spherical mirror is:

A student holding a mirror in his hand, directed the reflecting surface of the mirror towards the Sun. He then directed the reflected light on to a sheet of paper held close to the mirror.

Will he be able to determine the approximate value of focal length of this mirror from this activity ? Give reason and draw ray diagram to justify your answer in this case.

Write any three uses of plane mirror.

Define the following terms:

Spherical mirror.
