Enter the frequency corresponding to the energy difference (hz) into the Energy Difference Calculator. The calculator will evaluate the Energy Difference.

## Energy Difference Formula

The following two example problems outline the steps and information needed to calculate the Energy Difference.

dE = h*c/f

Variables:

• dE is the Energy Difference (Joules)
• f is the frequency corresponding to the energy difference (hz)
• h is Planck’s Constant (6.626 * 10^-34 J)
• c is the speed of light (2.998 * 10^8 m/s)

## How to Calculate Energy Difference?

The following steps outline how to calculate the Energy Difference.

1. First, determine the frequency corresponding to the energy difference (hz).
2. Next, gather the formula from above = dE = h*c/f.
3. Finally, calculate the Energy Difference.
4. After inserting the variables 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.

frequency corresponding to the energy difference (hz) = 300

dE = h*c/f = ?
