Question

Find the focal length of a convex mirror whose radius of curvature is 48 cm​

Answer 1

Answer:

Focal length is 24cm.

Explanation:

Given

-Radius of curvature,

R = 48cm

Radius of curvature = 2 x Focal length (f)

=> R = 2f

=> f = R/2

=> f = 48/2

=> f = 24cm

Answer 2

Answer: 24cm

Explanation:

The focal period of convex lens method is item distance elevated through the photo distance divided through the distinction of the item distance and the photo distance.

f=2R or focal period of a convex reflect is 1/2 of of its radius of curvature.

Given-Radius of curvature,

R = 48cm

Radius of curvature = 2 x Focal period (f)

=> R = 2f

=> f = R/2

=> f = 48/2

=> f = 24cm
