Energy from Wavenumber Formula
The following equation is used to calculate the Energy from Wavenumber.
E = -k*h
Variables:
- Where E is the Energy from Wavenumber (Joules)
- k is the wavenumber
- h is Planck’s Constant (6.62607004 * 10^-34)
To calculate energy from wavenumber, divide the wavenumber by Planck’s constant.
How to Calculate Energy from Wavenumber?
The following two example problems outline the steps and information needed in order to calculate the Energy from Wavenumber.
Example Problem #1:
- First, determine the wavenumber. In this example, the wavenumber is measured to be 1441.
- Finally, calculate the Energy from Wavenumber using the formula above:
E = -k*h
Inserting the values from above and solving the equation with the imputed values gives:
E = -6.62607004 * 10^-34*1441 = -9.54e-31 (Joules)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
wavenumber = 123561
Entering these values into the formula or calculator above gives us:
E = -6.62607004 * 10^-34*123561 = 8.18 e-29 (Joules)
