What is the energy in joules of a photon with a frequency of 5.6 * 10¹⁴ Hz? A) 3.7 * 10^-21 B) 6.8 * 10²⁰ C) 6.8 * 10^-¹⁹ D) 3.7 *10^-¹⁹ E) 3.7 *10¹⁹

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 $f = 5.6 \times 10^{14} \, \text{Hz}$, the energy $E$ is calculated as $E = 6.626 \times 10^{-34} \, \text{J}\cdot\text{s} \times 5.6 \times 10^{14} \, \text{Hz} = 3.71056 \times 10^{-19} \, \text{J}$, which rounds to $3.7 \times 10^{-19} \, \text{J}$, matching the format of option D.
