Question

Which statement is true about the energy of electromagnetic radiation?

A. The frequency of the emmited radiation is inversely proportional to its energy.
B. The frequency of the emitted radiation is directly proportional to its energy
C. The wavelength of the emitted radiation is directly proportional to its energy.
D. The amplitude of the emitted radiation is inversely proportional to its energy.

Answer 1

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.

Answer 2

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.
