Enter the total energy of radiation (J) into the Frequency of Radiation Calculator. The calculator will evaluate the Frequency of Radiation. 

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)

To calculate the frequency of radiation, divide the total energy by Planck’s constant.

How to Calculate the Frequency of Radiation?

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


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

total energy of radiation (J) = .0056

h = 6.62*10^-34

fr = E/h = ?
