WebOne simple answer (and there are actual, deeper physics answers) is that the light interacts with the material, and those interactions are wavelength dependent. And, red light doesn't … Web18. nov 2024 · Red light is produced by lower-energy photons than blue light is; if you use the same amount of energy for both red and blue sources, then the red light source will be brighter since less energy is used per photon. This means more photons can be produced.
