WebApr 1, 2014 · Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. Now there is an interesting additional effect contained in the general equation. If a particle has no mass ( m = 0) and is at rest ( p = 0), then the total energy is zero ( E = 0). WebThe photon energy at 1 Hz is equal to 6.62607015 × 10 −34 J That is equal to 4.135667697 × 10 −15 eV Electronvolt [ edit] Energy is often measured in electronvolts. To find the photon energy in electronvolts using the wavelength in micrometres, the equation is approximately This equation only holds if the wavelength is measured in micrometers.

WebApr 22, 2024 · relativistic mass is "transformed" by lorentz factor. invaritant mass, isn't "tranformed", and it is normally the mass that we use in classical mecanics, in expressions like: density=m/V, kinectic E=1/2mv^2, potential E=mgh and so1. relativistic mass, is used in modern mecanics, and is too "named" as energy, by the E=mcc. WebAug 28, 2004 · Gonzolo said: The short answer is that light doesn't have a rest mass. Only relativistic mass. And it is affected by gravity because gravity curves space-time. Gravity curves spacetime near a ray of light becouse light has momentum and energy, and those gravitate, along with the mass the light doesn't have. Aug 23, 2004.
WebDoes the photon have mass? After all, it has energy and energy is equivalent to mass. Photons are traditionally said to be massless. This is a figure of speech that physicists … In the case that the photon has mass, the mass term 1 / 2 m 2 A μ A μ would affect the galactic plasma. The fact that no such effects are seen implies an upper bound on the photon mass of m < 3 × 10 −27 eV/c 2.
