Does light lose energy as it travels
WebFeb 17, 2024 · When light waves move from one medium to another, the interaction between the photons (light) and the electrons of the object causes a change in wavelength. This will make the light appear as bent which will ultimately change the speed of light. Therefore, if the light into a denser medium, the light will slow down. Related: Does … WebThe photons spread out. And if a photon collides with something then it can get left behind. But a photon always has the energy of a photon, that's a physical constant. So all that's happing is a loss of the quantity of light. But the light that did manage to make it's way here has just as much energy as it did when it started out
