How does light have energy if it has no mass
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 ... WebDoes the photon have mass? After all, it has energy and energy is equivalent to mass. ... That way, equation (1) gives the correct expression for light, E = pc, and no harm has been done. Equation (1) is now able to be applied to particles of matter and "particles" of light. It can now be used as a fully general equation, and that makes it very ...

There are so many polit..." rayeesrather786Web27 Photons are massless, but if m = 0 and E = m c 2, then E = 0 c 2 = 0. This would say that photons have no energy, which is not true. However, given the formula E = ℎ f, a photon does have energy as ℎ is a non-zero constant and photons with a zero frequency do not exist. What am I missing here, or does the famous formula not apply to photons? simple supper meals instant potWebLight carries energy due to its momentum resulting from its speed. It doesn’t carry energy due to its mass. Mass and momentum are two separate factors that give an object or a particle it’s energy. If there is zero mass then the energy would be from its momentum. If the momentum is zero then the energy would be from its mass. simple supplements for working outWebLight 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.
