Question

If heat is received by a body from a source only by radiation, how is medium in between them, affected?

Solution
Verified by Toppr

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, the medium remains unaffected.

Statement - 1 : Due to the motion of listener, the frequency of the sound waves (as received by listener) emitted by stationary source is affected.
Statement - 2 : Due to the motion of source, wavelength of the sound waves (emitted by source) as received by stationary listener is affected.
Statement - 3 : If receiver and source both are moving, the observed frequency must be different from the original frequency of source.
Treat motion of source or listener as always along a line joining them for all above cases.
