A parallel beam of light, when incident on an optical device shows behaviour as shown in figure. The device is

A

convex lens

B

concave lens

C

concave mirror

D

plane glass slab of high refractive index

Text Solution

Verified by Experts

The correct Answer is:
B
From given figure, it is clear that given optical device is concave lens because light rays tum towards base of lens.
