Question

>>Can explain centre of curvature, principal axis through diagrams.​

Answer 1

To explain:

Centre of curvature and principal axis of spherical mirrors.

Explaination:

Centre of curvature is the centre point of the sphere from which the spherical mirror has been obtained.

• The distance of the mirror from the centre of curvature will be known as the radius of curvature.

• Any light ray passing through the centre of curvature is incident normally (at 90°) on the spherical mirror.

Principle axis:

• It is an imaginary line passing through the pole, principal focus and the centre of curvature of a spherical mirror.

Refer to the diagram to understand more. [Point "C" is the centre of curvature of the spherical mirror]
