Emission from a bodya.varies with frequency and temperatureb.varies with temperature onlyc.independent of temperature

The emission from a body can be explained by Planck's law of black body radiation. According to this law:

a. Emission from a body varies with frequency and temperature: This is true. The law states that the energy emitted at a particular frequency is proportional to the temperature of the body and the frequency of the radiation.

b. Emission from a body varies with temperature only: This is partially true. While the emission does increase with temperature, it also depends on the frequency of the radiation.

c. Emission from a body is independent of temperature: This is false. As stated above, the emission from a body increases with its temperature.
