Question

if the radius of curvature of a spherical mirror is 6 cm then find it's focal length​

Answer 1

Explanation:

f=1/2R

f=3 cm

This is the answer

Answer 2

Answer

Radius of curvature = 2 x focal length.

Radius of curvature = 2 x focal length.So, focal length =

Radius of curvature = 2 x focal length.So, focal length = 2

Radius of curvature = 2 x focal length.So, focal length = 21

Radius of curvature = 2 x focal length.So, focal length = 21

Radius of curvature = 2 x focal length.So, focal length = 21 × radius of curvature =

Radius of curvature = 2 x focal length.So, focal length = 21 × radius of curvature = 2

Radius of curvature = 2 x focal length.So, focal length = 21 × radius of curvature = 21

Radius of curvature = 2 x focal length.So, focal length = 21 × radius of curvature = 21

Radius of curvature = 2 x focal length.So, focal length = 21 × radius of curvature = 21 ×20 cm = 10 cm
