Question

Bi-Convex lens is made from two spheres of different radii, focus is marked from both spherical surfaces

and focal length is measured on both sides. Will focal length be equal on both sides? Imagine and write an

answer.​

Answer 1

Answer:

It depends on the thickness of the respective sides. But Yes it is possible to have equal focii both the sides.

Explanation:

Answer 2

Explanation:

The convex lens will be converging, i.e., will behave like a convex lens when n

1

>n

2

.

The same convex lens will be diverging, i.e., will behave like a concave lens when n

1

<n

2

So, the convex lens will behave like a convex or a concave lens depending on the values of n
