WebJan 12, 2015 · Kinetic Energy – This is the energy of the light due to its motion. Note that because a photon has no mass, its kinetic energy equals its total energy. The energy of light allows it to create a gravitational field according to General Relativity. As should be obvious, energy is just one of many properties that photons carry. WebWhen 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. This change in energy is directly proportional to the frequency of photon …
WebSep 22, 2014 · Light is composed of photons, which have no mass, so therefore light has no mass and can't weigh anything. Not so fast. Because photons have energy -- and, as Einstein taught us, energy is equal to the … WebThis is derived from the famous E = mc 2 relationship. Or rather, it’s bigger cousin: E 2 = m 2 c 4 + p 2 c 2. Where E is energy, m is mass, c is the speed of light in a vacuum, and p is momentum. Since photons have zero mass, the equation simplifies to E = pc, and therefore p = E/c. Thus, photons carry momentum because they have non-zero energy.
WebAnswer (1 of 22): Classically (according to Newton) kinetic energy is given by and momentum is given by ,where m is mass and v is velocity. But if you plug in the mass and …
