Enter the frequency and Planck’s constant into the calculator to determine the energy of the photon.

## Hz To Joules Formula

The following formula is used to calculate the energy of a photon from its frequency.

E = h * v

Variables:

- E is the energy of the photon (Joules)
- h is Planck’s constant (6.62607015 × 10^-34 m^2 kg / s)
- v is the frequency of the photon (Hz)

To calculate the energy of a photon, multiply the frequency of the photon by Planck’s constant. The result will be the energy of the photon in Joules.

## 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. However, in the context of quantum mechanics, the energy of a photon can be calculated from its frequency (in Hz) using the Planck-Einstein relation, E=hv, where E is energy in Joules, h is Planck’s constant, and v is frequency in Hz.

## How to Calculate Hz To Joules?

The following steps outline how to calculate the energy of a photon (E) in Joules using the formula E = h * v.

- First, determine the value of Planck’s constant (h). In this case, h = 6.62607015 × 10^-34 m^2 kg / s.
- Next, determine the frequency of the photon (v) in Hz.
- Next, use the formula E = h * v to calculate the energy of the photon (E) in Joules.
- Finally, calculate the energy of the photon (E) using the values of h and v.
- After inserting the values and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.
