Energy to Wavelength Calculator

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 the conversion of the total energy contained within a photon into the wavelength.

Energy to Wavelength Example

How to calculate energy to wavelength?

  1. First, determine the speed of light.

    This will be constant at the value of (299,792,458 m/s)

  2. Next, determine the plank constant.

    This will be constant at (6.6261*10^-34)

  3. Next, determine the total energy.

    Calculate the total energy of the photon.

  4. Finally, calculate the wavelength.

    Convert the energy to wavelength using the equation above.

FAQ

What is a wavelength?

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