WebIf we set the rest mass equal to zero (regardless of whether or not that's a reasonable thing to do), then E = pc . In classical electromagnetic theory, light turns out to have energy E and momentum p , and these happen to be related by E = pc . Quantum mechanics introduces the idea that light can be viewed as a collection of "particles": photons. WebA photon particle does not have any mass (because you cannot “weigh” light), so it is not considered to be matter. Scientists call a particle of light a photon because it can carry and pass on energy like matter can, but it also sometimes acts like a wave, as light should.

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. WebAug 28, 2004 · 11. 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.

WebDec 17, 2024 · Short answer: no. Explanation: Light does not have mass. However, light does exhibit some important properties that you might relate to something with mass. Some examples are Momentum If we model light as a stream of particles (photons) then the photons carry a momentum that can change the photon's energy into kinetic. WebSo light has mass on the basis of Newton's gravitational law . By the newton’s universal law of gravitation, F=G(M1*M2)/R^2 where, m1=mass of heavenly body r=distance …

WebLight actually carries energy without any mass. The above equation is actually a special case of the equation E² =p²c² + m²c⁴ where p is the momentum of the particle and c is the speed of light. It shows that the total energy of a particle is the combination of the mass energy and the motion energy of the particle.
