21 x 10-7 m, in the ultraviolet part of the spectrum. Why does the wavelength determine a photons energy? In the 19th century, it was thought that the energy of light was determined only by its intensity.It was Max Planck, not Albert Einstein, who found the right equation for black body radiation. This is because the photons are in the X-ray spectrum, and therefore they are more dangerous. The wavelength of a photon that has 1000 times as much energy as a photon a wavelength of 511 nm is nm. More specifically, photons are wave packets that contain a certain wavelength and frequency as determined by the type of light.More Articles.
