KIDS TRIVIA

Detailed explanation-1: -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 in the form of visible light. Light is made of waves of different frequencies.

Detailed explanation-2: -In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one. When objects transfer heat, they cool down to a lower temperature unless the heat energy they lose is constantly replaced.

Detailed explanation-3: -Thermal radiation is electromagnetic radiation emitted from a material that is due to the heat of the material, the characteristics of which depend on its temperature. An example of thermal radiation is the infrared radiation emitted by a common household radiator or electric heater.

Detailed explanation-4: -Defining Radiation Heat Transfer Radiation heat transfer occurs via electromagnetic waves. Unlike conduction and convection, radiation does not need a medium for transmission. Solar radiation energy traverses a 93-million-mile vacuum to warm the earth.

Detailed explanation-5: -Answer and Explanation: The radiant heat energy travels in the form of electromagnetic waves. When the heat energy travels in the form of electromagnetic waves, it is called radiant energy.
