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 … WebThat depends on your definition of mass. If you mean the inertial mass m, as in momentum p =m v, where v is the velocity, the answer is yes. That's the same m which is given by E/c 2. Since light has energy and momentum, it obviously has m in this sense of the term. If you mean rest mass, also called invariant mass, the answer
WebAnswer (1 of 6): In order to understand better, let us bring the fact that light is made up of small packets of particles called Photons. They are product of Plank’s constant times … WebLight is made up of packets of energy known as photons. So by Einstein’s famous equation linking energy and mass, E = mc 2, photons do have mass-like properties such as …
WebWhen the particle is at rest, its relativistic mass has a minimum value called the "rest mass" m rest. The rest mass is always the same for the same type of particle. For example, all protons have identical rest masses, and so do all electrons, and so do all neutrons; these masses can be looked up in a table.
