Wavenumber to Energy Calculator


About Wavenumber to Energy Calculator (Formula)

The Wavenumber to Energy Calculator is a handy tool that allows you to convert a wavenumber value into its corresponding energy value using a simple formula. This calculator is particularly useful in fields such as physics and spectroscopy, where the relationship between wavenumber and energy is crucial in understanding the behaviour of waves and particles.

The formula used by the calculator is:

E = -k * h

In this formula, “E” represents the energy, “k” denotes the wavenumber, and “h” is the Planck’s constant. The negative sign (-) is included to account for the inverse relationship between wavenumber and energy.

To use the calculator, you simply need to enter the wavenumber value into the input field and click the “Calculate” button. The JavaScript function associated with the button will retrieve the wavenumber value, perform the necessary calculations using the provided formula, and display the calculated energy value on the screen.

It’s important to note that Planck’s constant (h) is a fundamental constant in quantum mechanics, with an approximate value of 6.62607015e-34 Joule-seconds (J·s). The calculator incorporates this constant to accurately convert the wavenumber into its corresponding energy.

By utilising the Wavenumber to Energy Calculator, you can quickly obtain the energy value associated with a given wavenumber, enabling you to analyse and interpret wave phenomena and particle behaviour more effectively.
