(c) Principal axis
(d) Concave mirror
mirror
(e) Centre of curvature​

Answer 1

Answer:

1-b , 2-c, 3-e , 4-d , 5-a

Explanation:

Centre of curvature is the centre of the sphere of which the spherical mirror is a part.

Principal focus is a point on the principal axis, where a beam of light, parallel to the principal axis, after reflection, either actually meets (concave) or appears to meet (convex).

Radius of curvature is the linear distance between the pole and the centre of curvature.

Principal axis is an imaginary line passing through the pole and the centre of curvature of a spherical mirror.

Pole is the mid point of a spherical mirror.

Focal length is the linear distance between the pole and the principal axis
