Question

A convex lens has a focal length of 12cm.what is the distance between the optical center and the center of curvature (c)

Answer 1

Answer:

focal length measure from optical center to focus is 12 cm and we know F=C/2 then C is 24 cm

Answer 2

Answer:

The distance between the optical centre and the centre of curvature is 12cm.

Explanation:

Given,  focal length of a convex lens = 12cm.

• The distance between the optical centre and the main Focus is known as the focal length of a convex lens and is represented by the symbol f.

• The term "focal length" refers to the distance between the optic centre and the centre of curvature.

• So, focal length = distance between the optic center and the center of curvature.

Therefore, from the question we have,

Focal length of a convex lens  = 12cm

Hence, the distance between the optical centre and the centre of curvature = 12cm
