Consider the following statements about electromagnetic radiation and decide whether they are true or false. If they are false, correct them. (a) The total intensity of radiation emitted from a black body at absolute temperature T is directly proportional to the temperature. (b) As the temperature of a black body increases, the wavelength at which the maximum intensity is found decreases. (c) Photons of radio-frequency radiation are higher in energy than photons of ultraviolet radiation. (d) Photons of ultraviolet radiation have less energy than photons of infrared radiation. (e) The kinetic energy of an electron ejected from a metal surface when the metal is irradiated with ultraviolet radiation is independent of the frequency of the radiation. (f) The energy of a photon is inversely proportional to the wavelength of the radiation.
