A Photon has a wavelength of 698 nm. What is the frequency of the photon?

Solution

The connection between the mentioned parameters is: $\nu = c / \lambda$ .

$$v = 2.998 \times 10^{8} \, \text{ms}^{-1} / 698 \times 10^{-9} \, \text{m} = 4.295 \times 10^{14} \, \text{Hz}.$$

Answer: $4.295 \times 10^{14} \, \text{Hz}$ .
