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 … WebDoes the photon have mass? After all, it has energy and energy is equivalent to mass. ... That way, equation (1) gives the correct expression for light, E = pc, and no harm has been done. Equation (1) is now able to be applied to particles of matter and "particles" of light. It can now be used as a fully general equation, and that makes it very ...
If light has no mass, and mass is energy, how does light …
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. WebNov 14, 2024 · Why Light and Heat Aren't Matter. The universe consists of both matter and energy.

WebMar 7, 2024 · That being said, you can see and feel light, but you can’t see space. News alert, recent experiments have shown that a photon has a tiny mass with a new upper limit of 7 × 10−17 eV. Scientists don't want the photon to have mass because it complicates many equations and makes Einstein's idea of gravity false. 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. float_bytes pack f float_value
