Calculate Photon Energy using Planck's Constant

Calculator that calculate the photon energy using Plancks constant. A photon is characterized by either a wavelength, denoted by λ or equivalently an energy, denoted by E. There is an inverse relationship between the energy of a photon and the wavelength of the light given by the equation.


Energy of Photon (E) =hc/λ or E =hv
h=planck's constant (6.6260695729x10-34), c=velocity of light ( 2.99792458x108), λ=Wavelength, v=Frequency

We can find the energy of a photon with wavelength or we can also find the energy of a photon with frequency. We can input the value in the input-box of Wavelength of light or Frequency of light.
