The energy of a photon is given by:
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon,
, so we can rearrange the equation to calculate the frequency of the photon:
And now we can use the following relationship between frequency f, wavelength
and speed of light c to find the wavelength of the photon:
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon,
And now we can use the following relationship between frequency f, wavelength
