Question 13

Observe the given figures carefully

The given figures show the path of light through lenses of two different types, represented by rectangular boxes A and B. What is the nature of lenses A and B?

Answer 1

In the first case, light rays are converging towards a point, so the lens A will be a convex lens and in case of lens B, light rays diverge or spread out. So, the lens B will be a concave lens.
