Applications of radiation in our daily life:
It is more comfortable to wear white clothes in the hot summer than
black clothes because they absorb less radiant energy. A fire fighting suit
is bright and shiny, so that it does not take in a lot of heat energy.
2. Coffee or tea stays hot for a longer time in a shiny pot rather than in a
blackened one because shiny pot is a poor radiator of radiant energy.
3. A light-coloured building stays cooler in summer because it reflects most
of the heat radiation from the sun. It is also a poor emitter of heat and
stays warm in winter
4. The radiators of automobile engines are painted black because heat
generated by the engine is efficiently radiated.
5. The underside of cooking vessels are made black but sides are made
shiny. It is because the black surface absorbs radiant heat rapidly from
the fire.
