Question

5. On what factors does the focal length of lens depends?​

Answer 1

Answer:

Heyy

Explanation:

Medium in which the mirror or image is

Distance of object

the focal length depends upon the color of light. Now, by the lens maker formula which is, 1f=(μ−1)(1R1−1R2),where R1,R2 are radius of curvature of the two sides of the lens, hence focal length of the lens also depends upon the radius of curvature of the lens used.

Hope it helps

Answer 2

it depends on the

1) radius of curvature

2) the index of the refraction of the material from which lens is made

( refractive index )
