How does light have energy if it has no mass
WebA massless particle can have energy E and momentum p because mass is related to these by the equation m2 = E2/c4 - p2/c2, which is zero for a photon because E = pc for … WebAug 16, 2011 · If light had no mass (no energy) it would pass through objects sure. But it does have mass. You read that it can be treated as a particle with zero rest mass, this …
How does light have energy if it has no mass
Did you know?
WebLight has no rest mass, but it is possible to think of it as having a 'relativistic mass' by applying m = E / c 2 with no regard to the gamma factor. However, this does not mean that light has mass in any meaningful way - it is simply a measure of how much mass a … If light has energy, does it have mass? See more linked questions. Related. 12. … WebIf we set the rest mass equal to zero (regardless of whether or not that's a reasonable thing to do), then E = pc . In classical electromagnetic theory, light turns out to have energy E and momentum p , and these happen to be related by E = pc . Quantum mechanics introduces the idea that light can be viewed as a collection of "particles": photons.

WebLight is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass. On the other hand, if light does have mass then doesn't mass become infinitely larger the closer to the speed of light an object travels.

Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass. (For details see red potatoes toaster ovenWebMar 16, 2010 · 4,793. 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 ... rich jobs in the 1920sWebWhen 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.
