Energy of a Photon

The Energy of a Photon equation is used to find the Energy that a photon of light possesses where:

• `h` = Plank's constant
• `f` = frequency

Energy(E): The equation returns the Energy in Joules. However, this can be automatically converted to other energy units via the pull-down menu.

Energy, Photon and Wavelength Calculators

• Quantum Energy (E=h⋅v): Computes radiant energy in the Planck-Einstein relationship (E = h•ν) based on Planck's constant and a frequency of radiation.
• Energy of a Photon (E=h⋅f): Computes the energy of a photon based on the frequency and Planck's Constant.
• Photon Energy from Wavelength (E=(h⋅c)/λ): Computes the energy of a photon based on Planck's constant (h), the speed of light (c) and the wavelength of the photon ( λ)
• Photon Wavelength form Energy (λ=(h⋅c)/E): Computes the wavelength of a photon based on Planck's constant (h), the speed of light (c) and the energy of the photon (E).
• DeBroglie Wavelength (λ=h/(m⋅v)): Computes the wavelength of a particle based on the Planck's Constant and momentum (p = m•v).
• Plank Constant (h):  Fundamental constant in physics that plays a central role in quantum mechanics which relates the energy of a photon to its frequency
