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 … 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. WebJun 11, 2013 · Light does carry momentum. 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. flowering pots for sale

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. 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.

This would say that photons have no energy, which is not true. However, given the formula E = ℎ f, a photon does have energy as ℎ is a non-zero constant and photons with a zero frequency do not exist. What am I missing here, or does the famous formula not apply to photons?

WebLight carries energy due to its momentum resulting from its speed. It doesn’t carry energy due to its mass. Mass and momentum are two separate factors that give an object or a particle it’s energy. If there is zero mass then the energy would be from its momentum. If the momentum is zero then the energy would be from its mass. 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.
