Question

Quizplus · Accepted Answer

The frequency ($f$) of a photon can be calculated using the equation $E = hf$, where $E$ is the energy of the photon, $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{Js}$), and $f$ is the frequency. Rearranging the equation to solve for $f$, we get $f = \frac{E}{h}$. Substituting $E = 8.10 \times 10^{-19} \, \text{J}$ and $h = 6.626 \times 10^{-34} \, \text{Js}$, we find $f = \frac{8.10 \times 10^{-19}}{6.626 \times 10^{-34}} = 1.22 \times 10^{15} \, \text{Hz}$.
