The Photon Wavelength from Energy calculator compute the wavelength ( λ) of a photon based on Planck's constant (h), the speed of light (c) and the energy of the photon ( E).
INSTRUCTIONS: Choose units and enter the following:
Wavelength of Photon (λ): The calculator returns the wavelength in meters. However, this can be automatically converted to compatible units via the pull-down menu.
The energy of a photon depends only on its wavelength. Theis:
The Astronomy Calculator Suite includes functions that are useful for studying astronomy and include the following:
