Spherical mirror

Question 1

What do you mean by spherical mirror?

Answer 1

A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass

Question 2

What is a concave mirror?

Answer 2

A spherical mirror whose reflecting surface is curved inwards.

Question 3

What is a convex mirror?

Answer 3

A spherical mirror whose reflecting surface is curved outwards.

Question 4

Pole?

Answer 4

The centre of a reflecting surface of a spherical mirror

Question 5

Centre of curvature

Answer 5

The centre of curvature of a spherical mirror is the centre of a hollow sphere of glass in which the mirror is a part

Question 6

Radius of curvature

Answer 6

The radius of curvature of a spherical mirror is the radius of a hollow sphere of glass in which the mirror is a part

Question 7

Principal axis

Answer 7

the straight line passing through the centre of curvature and pole of the spherical mirror

Question 8

Aperture

Answer 8

The diameter of the reflecting surface of spherical mirror

Question 9

Principal focus

Answer 9

It is a point on its principal axis in which the light rays either converge in concave mirror or diverge in convex mirror to form it
