Question

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula $E = \frac{hc}{\lambda}$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{m}^2 \, \text{kg} / \text{s}$), $c$ is the speed of light ($3.00 \times 10^8 \, \text{m/s}$), and $\lambda$ is the wavelength of the light (in meters). For yellow light with a wavelength of 589 nm (which is $589 \times 10^{-9}$ meters), the calculation yields an energy value of approximately $3.37 \times 10^{-19}$ Joules.
