Green light has a wavelength of 5.4 × 10−⁷ m. What is the frequency of this EM-wave in air?

Question

Quizplus · Accepted Answer

The frequency $f$ of an electromagnetic wave is given by the equation $f = \frac{c}{\lambda}$, where $c$ is the speed of light in vacuum (approximately $3.00 \times 10^8$ m/s) and $\lambda$ is the wavelength of the light. Given the wavelength of green light as $5.4 \times 10^{-7}$ m, the frequency is calculated as $f = \frac{3.00 \times 10^8 \, \text{m/s}}{5.4 \times 10^{-7} \, \text{m}} = 5.55 \times 10^{14}$ Hz.
