The figure shows the spectral distribution of radiant energy from a black body at temperature T.

Select all that apply

• Option A

  The radiant energy is not equally distributed among all the possible wavelengths

• Option B

  For a particular wavelength the spectral intensity is maximum

• Option C

  The area under the curve is equal to the total rate at which heat is radiated by the body at that temperature

• Option D

  None of these

Select all that apply

• Option A

  The intensity of radiation for every wavelength increases

• Option B

  The maximum intensity occurs at a shorter wavelength

• Option C

  The area under the graph increases

• Option D

  The area under the graph is proportional to the fourth power of temperature
