WebWhen an atom or molecule loses energy, it emits a photon that carries an energy exactly equal to the loss in energy of the atom or molecule. This change in energy is directly proportional to the frequency of photon … WebLight energy is of various types. They are: Visible light – Can only be seen through the naked eye. It’s a form of electromagnetic energy. The source of visible light is the sun. It can …
WebNov 26, 2024 · That’s not all. When 3 photons stuck together resembling an atom they measured a small mass. This was proof that light has mass! How can a massless wave … WebFirst you cannot treat the energy of a classical light wave the same way as the energy of a photon. The energy of a photon is E = hf. The energy of a light wave is proportional to the square of the amplitude of oscillation of …
WebAug 16, 2011 · If light had no mass (no energy) it would pass through objects sure. But it does have mass.

FizixFreak said: you travel close to the speed of light you mass varies it is proven by theory of relativity. It depends on which definition of "mass" you use. In classical physics, there is only one "mass" which is used in several ways. In relativity, this isn't true. People have developed different concepts of "mass" in relativity, and ...
WebDec 29, 2006 · Only the mass increases, the size (to an outside observer) actually decreases in the direction the particle is traveling. Light does not have mass. Under General Relativity, you don't need to have mass to be affected by gravity. Only things with no mass can travel at the speed of light. Quantum Mechanics says that things can be both particles ...
