What is the energy (E, in joules) of a 6.00 * 10¹⁰ Hz photon from a microwave oven?

Question

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula $E = hf$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{J}\cdot\text{s}$) and $f$ is the frequency of the photon. Given the frequency is $6.00 \times 10^{10} \, \text{Hz}$, the energy $E = (6.626 \times 10^{-34} \, \text{J}\cdot\text{s}) \times (6.00 \times 10^{10} \, \text{Hz}) = 3.98 \times 10^{-23} \, \text{J}$, which matches choice C.
