Question

Which statement is true about the energy of electromagnetic radiation?

Answer 1

The energy released by the wave during its motion is calculated through the following equation,
                                      E = hcf
where E is energy, h is a constant, c is the speed of light in a vacuum, and f is the frequency. Evidently, the frequency of the radiation is directly proportional to its energy. 

Answer 2

Answer: Hi!

The energy of an electromagnetic wave is E = hv, where v is the frequency of the wave, and h is the planck's constant, h = $6.62607015*10^{-34} J*s$. So the correct answer is that the frequency of emitted radiation is directly proportional to its energy.
