Question

Name the process by which you receive heat from sun.

• A. thermal radiation
• B. conduction
• C. convention
• D. none of these

Answer 1

The correct option is A thermal radiation

Thermal Radiation occurs through a vacuum or any transparent medium (solid or fluid). It is the transfer of energy by means of photons in electromagnetic waves.Thermal radiation is a direct result of the random movements of atoms and molecules in matter. Since these atoms and molecules are composed of charged particles (protons and electrons), their movement results in the emission of electromagnetic radiation, which carries energy away from the surface.

So we receive heat from sun by thermal radiation.
