Question

State the lens maker formula and explai the terms in it​

Answer 1

Answer:

The lens maker formula gives the relationship between focal length, radius of curvature and the refractive index of the lens. F is negative. Hence, this is the required solution.

Explanation:

Answer 2

Answer:

Lens maker's formula:

where, f is focal length

n
