WebLight has no mass, so it's momentum is can be written as p = h/λ. Where h is the Planck constant and λ is the De Broglie wavelength. The energy of an object can be determined by the following equation: E 2 = c 2 p 2 + m* 0 * 2 c 4 Where c is the speed of light, p is the objects momentum, and m* 0 * is the objects invariant mass. Web8 de set. de 2007 · Simply, no. Einsteins famous equation E=mc^2 shows us that energy and mass are directly proportional, so without mass, the value of E= 0. But after thinking some more it doesn't seem like such an easy answer. For example, light carries both energy and momentum in the form of photons, yet photons are said to be massless.

WebIf light can somehow push the atom, a countering light could slow down the atom’s speed. Maybe surprisingly, light does have this ability. Although the light has no mass, it does contain momentum, which is the ability to push something. Since the momentum of light is quite small, a heavy object like we humans would literary be not pushed.
