Question:

What amount of energy is contained in a single photon of orange light with a frequency of $5.00 \times 10^{14} \, \text{s}^{-1}$?

Solution:

The link between the energy of photon and frequency is:

$$E = h \nu,$$

where $h$ is Planck's constant, $\nu$ is frequency and $E$ is energy.

$$E = 6.63 \cdot 10^{-34} (m^2 \cdot kg \cdot s^{-1}) \cdot 5 \cdot 10^{14} (s^{-1}) = 3.32 \cdot 10^{-19} J$$

Answer: $3.32 \cdot 10^{-19} J$
