WebNov 26, 2024 · The mass of one photon is extremely small at less than 1 x 10^-18 eV/c^2. However, light beams are made up of millions of photons therefore, the mass of light is real. Furthermore, light has momentum and relativistic mass in the form of energy. The real meaning of this is mind blowing news to the theory of spacetime. 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.

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. trying add usb printer windows going on loop

Momentum can be thought of as an object's ability to push another object due to its motion. Classically, momentum is defined as the mass of the object times the velocity of the object, p = mv. Since light has no mass, you may be tempted to say that light has no momentum.

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 .
