option(2)

CONCEPT:

  • Black body: Those type of body that neither reflect nor transmits but absorbs the whole of the heat radiation called the black body.
    • Energy distribution of black body radiation state that when wavelength increases, the energy emitted from the black body radiation will also be increasing.

EXPLANATION:

  • The Energy Distribution curve as shown in the figure concludes that:

F2 J.K 14.8.20 Pallavi D11

  • As the wavelength increases, the energy emitted increases and reaches the maximum height. After this point, it started decreasing gradually.
  • Hence we can say that the Energy distribution of black body radiation state that when wavelength increases, the energy emitted from the black body radiation will increase first and then decreases.
  • Hence option 2 is correct.
