The correct answer is a) Material W is less absorbent than material Z
Absorption is the transfer of the energy of a wave to matter as the wave passes through it .
Reflection is the abrupt change in the direction of propagation of a wave that strikes the boundary between different medium .
The material which is good absorber will have high temperature because of of more heat is absorbed and less is reflected whereas the material which is good reflector will reflect more and absorb less due to which it will have less temperature as less heat is being absorbed and more is being reflected by that material .
correct answer is a) Material W is less absorbent than material Z as temperature of W is lowest which means it absorbed less heat whereas Z have highest temperature that means it absorbed more heat .
