The plots of energy density (energy per unit area) vs wavelength for blackbody radiation at various temperatures is given below.
The correct option among the following is:
(i) (ii) As temperature increases, the wavelength at which the intensity is maximum shifts towards the higher energy regions of the electromagnetic spectrum. (iii) Radiations of all wave lengths are emitted, absorbed, reflected, and refracted by the black body. (iv) The total energy density increases as the temperature is decreased.
