Question

The ratio of energy to frequency of electromagnetic radiation is equal to _____

Answer 1

1. According to Planck's quantum theory of radiation, the amount of energy associated with a quantum of radiation is proportional to the frequency of radiation by an equation $\mathrm{E}=\mathrm{h\nu }—\left(1\right)$.
2. In equation $\left(1\right)$, $\text{'}\mathrm{E}\text{'}$ is the energy of radiation, $\text{'}\mathrm{h}\text{'}$ is Planck's constant and $\text{'}\mathrm{\nu }\text{'}$ is the frequency of radiation.
3. The Plank's constant relates the energy possessed by a single electron to its corresponding frequency and its value is $6.626\times {10}^{-34}\text{J}$.

Therefore, the ratio of energy to frequency of electromagnetic radiation is equal to Plank's constant.
