Enter the total energy of a photon into the calculator to determine the wavelength.

## Energy to Wavelength Formula

The following equation can be used to convert energy into a wavelength for photons.

w = h *c / E

- Where w is the wavelength
- h is the Planck constant (6.6261*10^-34)
- c is the speed of light (299,792,458 m/s)
- E is the energy

## Energy To Wavelength Definition

Energy to wavelength is defined as the conversion of the total energy contained within a photon into the wavelength.

## Energy to Wavelength Example

How to calculate energy to wavelength?

**First, determine the speed of light.**This will be constant at the value of (299,792,458 m/s)

**Next, determine the plank constant.**This will be constant at (6.6261*10^-34)

**Next, determine the total energy.**Calculate the total energy of the photon.

**Finally, calculate the wavelength.**Convert the energy to wavelength using the equation above.

## FAQ

**What is a wavelength?**

A wavelength is a distance a photon travels as it completes one full-wave or frequency.

**What is the planck constant?**
