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.
How does light have energy if it has no mass
Did you know?
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. … WebSince photons have zero rest mass then their energy is simply E = pc. The fact that light carries momentum is also verified by experiment. The other issue you raise, the fact that …
WebEven though photons have no mass, they still have momentum proportional to their energy, given by the formula p=E/c. Because photons have no mass, all of the momentum of a photon actually comes from its energy and frequency as described by the Planck-Einstein relation E=hf, and NOT E=MC squared. 3 UntangledQubit • 1 yr. ago WebLight is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass. On the other hand, if light does have mass then doesn't mass become infinitely larger the closer to the speed of light an object travels.
WebSep 27, 2011 · a) light is subject to gravity it loses energy climbing out of the gravitational well of a star or a planet and is deflected by it as it passes this energy loss and deflection … WebSep 27, 2011 · a) light is subject to gravity it loses energy climbing out of the gravitational well of a star or a planet and is deflected by it as it passes this energy loss and deflection is very small for normal gravitational fields but has been measured many times and corresponds exactly to theory.
WebFirst you cannot treat the energy of a classical light wave the same way as the energy of a photon. The energy of a photon is E = hf. The energy of a light wave is proportional to the square of the amplitude of oscillation of …
WebAug 25, 2024 · has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass. (For details see cut and paste stopped workingWebLight 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. cheap 5-bed houses for sale mesogiWebAug 16, 2011 · If light had no mass (no energy) it would pass through objects sure. But it does have mass. You read that it can be treated as a particle with zero rest mass, this … cheap 5 bedroom houses for sale near meWebLight energy is of various types.
