Answer: D) The lower the radiant energy, the lower frequency and the longer the wavelength.

Explanation: The energy of the electromagnetic radiations is directly proportional to frequency of the radiation and is inversely proportional to the wavelength of the radiation. Thus if frequency is low, the energy is low and the wavelength is long.

E=h\nu

\nu=\frac{c}{\lambda}

Thus E=\frac{hc}{\lambda}

E = energy

h= planck's constant

c= velocity of light

\nu= frequency
