Question

i) Define radius of curvature and focal length of a spherical mirror.

ii)Write relation between radius of curvature and focal length of a spherical

mirror​

Answer 1

Answer:

Hey Mate!!

i) Radius of curvature is the centre of the sphere of which the mirror is a part.

Focal length is the distance between the pole and focus of a spherical mirror.

ii) 2f = R

Where f is focal length and R is radius of curvature.

Answer 2

Answer:

(i)The radius of curvature is the distance from the pole.

The focal length is the distance between the pole and the principle focous.

(ii)The relation between the radius of curvature R and focal length is the reciprocal of the curvature.
