WebThe idea that light has no mass but can have an energy value seems wrong to me. Following Einstein's E = m x c^2 Light has a value in energy because any photon or single packet of light has measurable energy value. Therefore the equation says there must be a mass for this energy to exist.

Where do photons go when they are absorbed?

WebIn other words, a photon does have relativistic mass proportional to its momentum. De Broglie's relation, an early result of quantum theory (specifically wave-particle duality), states that λ = h / p where h is simply Planck's constant. This gives p = h / λ Hence combining the two results, we get E / c 2 = m = p c = h λ c WebWhat is the mass of a photon? This question falls into two parts: Does the photon have mass?
