Question

State two applications of radiations.

Answer 1

Two applications of radiation are as follows:

1. White or light coloured clothes are good reflectors of heat. Therefore, they are preferred in summers as they reflect (radiate) most of the heat from the Sun, thereby keeping our bodies cool.
2. Black colour is a good absorber as well as a good radiator of heat. Therefore, the bases of cooking utensils are usually painted black so that they can absorb more heat and food can be cooked faster.
