The sun's rays are falling on two identical ice blocks as shown in the figure Then

A

block 'A' starts melting first.

B

block 'B'starts melting first.

C

both starts melting at the same time.

D

Cannot be compared

Text Solution

Verified by Experts

The correct Answer is:
A
Normal incidence is the condition for maximum absorption of heat radiation, and hence, ice block A starts melting first.
