EVERYDAY SCIENCE

Detailed explanation-1: -Burning logs produce energy in the form of light waves. Flames are a combination of different types of light waves of different energy. When these light waves are absorbed by the body of the dog, the energy of light converts into heat, warming the dog’s body. Hence moving energy in form of waves if radiation.

Detailed explanation-2: -When you sit by a campfire, most of the heat you are receiving from the fire does not come from hot air. It comes from thermal radiation.

Detailed explanation-3: -Fire emits electromagnetic radiation that travels in invisible waves through space. When these waves hit a combustible material or a person, the radiant energy is absorbed and converted into heat.

Detailed explanation-4: -Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
