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.

WebWhat is the mass of a photon? This question falls into two parts: Does the photon have mass? After all, it has energy and energy is equivalent to mass. Photons are traditionally … WebDo photons carry mass as suggested by the equation m = hf/c2 ? If you take Einstein's equation E = m c^2 , where m = mass and c = speed of light, and the Planck equation for the energy of a photon, E = h f , where h = Planck's constant and f = the frequency of the photon, and combine them you get: m c^2 = hf or that m = h f/c^2. stranger in the village james baldwin quotes
