Start by recalling the relationship between energy and wavelength, which is given by the equation: , where is the energy of the photon, is Planck's constant, is the speed of light, and is the wavelength.
Rearrange the equation to solve for wavelength: . This will allow you to find the wavelength when you know the energy of the photon.
Substitute the known values into the equation. Use Planck's constant = J·s and the speed of light = m/s.
Calculate the wavelength in meters using the formula: .
Convert the wavelength from meters to nanometers by multiplying the result by , since 1 meter = nanometers.
