## Frequency of Radiation Formula

The following two example problems outline the steps and information needed to calculate the Frequency of Radiation.

**fr = E/h**

Variables:

- fr is the Frequency of Radiation (hz)
- E is the total energy of radiation (J)
- h is Planck’s constant = 6.62*10^-34 (J-s)

## How to Calculate Frequency of Radiation?

The following steps outline how to calculate the Frequency of Radiation.

- First, determine the total energy of radiation (J).
- Next, gather the formula from above = fr = E/h.
- Finally, calculate the Frequency of Radiation.
- 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.

total energy of radiation (J) = .0056

h = 6.62*10^-34

fr = E/h** **= ?
