Question

The radius of curvature of a spherical mirror is 100cm. What is its focal length ?​

Answer 1

Answer:

Hence, the focal length of the given spherical mirror is 50cm.

Explanation:

Given-

Radius of curvature,

R = 100 cm

Radius of curvature of a spherical mirror

= > 2 x focal length(f)

=> R = 2f

=> f = R/2

=> f = 100/2

=> f = 50cm.

Hence, the focal length of the given spherical mirror is 50cm.

Answer 2

Answer:

we know R = 2F

F = R/2

F= 100/2

= 50 cm
