1 of 1

Understanding +4 | -1

Statement-A: A lens has low principal focal lengths which may differ.

Statement-B: Light can fall on either surface of the lens. The two principal focal lengths differ when medium on the two sides have different refractive indices.

View answer and explanation

Correct option: A

A and B are correct

Option A is correct because a lens can have different focal lengths, and these differ if the refractive indices of the surrounding media are different.
