Enter the Planck’s constant and the frequency into the Calculator. The calculator will evaluate the Photoelectric Effect Energy. 

Photoelectric Effect Energy Formula

E = h*v


  • E is the Photoelectric Effect Energy (joules)
  • h (J-s) is the Planck’s constant
  • v (hz) is the frequency

To calculate Photoelectric Effect Energy, multiply Planck’s constant by the frequency.

How to Calculate Photoelectric Effect Energy?

The following steps outline how to calculate the Photoelectric Effect Energy.

  1. First, determine the Planck’s constant. 
  2. Next, determine the frequency. 
  3. Next, gather the formula from above = E = h*v.
  4. Finally, calculate the Photoelectric Effect Energy.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :
