Hz to Joules Calculator

Formula

The formula to calculate the energy of a photon (E) from its frequency (v) is:

$\text{E} = h \times v$

Where:

$\text{E}$ is the Energy of the Photon (Joules)
$h$ is Planck's Constant ( $6.62607015 \times 10^{-34}$ m² kg / s)
$v$ is the Frequency of the Photon (Hz)

What is Hz to Joules?

Hz (Hertz) and Joules are units of measurement in physics but they measure different things. Hz is a unit of frequency, measuring the number of cycles per second. On the other hand, Joules is a unit of energy, work, or amount of heat. There isn’t a direct conversion from Hz to Joules because they measure different things.

Example Calculation

Let's consider an example:

Frequency (v): 5 × 10¹⁴ Hz

Using the formula to calculate the energy of the photon:

$\text{E} = 6.62607015 \times 10^{-34} \times 5 \times 10^{14} = 3.313035075 \times 10^{-19} \, \text{Joules}$

This demonstrates that with a frequency of 5 × 10¹⁴ Hz, the energy of the photon would be approximately 3.31 × 10^-19 Joules.
