Q: How can photons have energy and momentum, but no mass?

Web5 de mar. de 2024 · Let the momentum of a certain light wave be (pt, px) = (E, E), and let another such wave have momentum (E, − E). The total momentum is (2E, 0). Thus this pair of massless particles has a collective mass of 2E. This is an example of the non-additivity of relativistic mass. Collision Invariants WebIn my opinion, zero mass object may have non-zero momentum as long as its speed equals to c. It will bring its Lorentz factor (γ) to infinity.

"Web30 de out. de 2024 · In classical mechanics, momentum ( p) is proportional to the mass and the velocity of an object ( p = m v) and kinetic energy is E k = 1 2 m v 2. Thus you might think photon has no momentum and energy since mass is zero. However, according to the relativistic theory, all these formula is changed. " - How can light have momentum without mass

In this way, waves can have no mass but still carry …

WebThis is, of course, the famous equation E=mc 2, however, it highlights an important point; mass is simply another form of energy, namely, the energy that any particle has at rest.This IS the fundamental definition of mass. Based on this, we can also intuitively reason why a photon does not have mass and it comes from another prediction of special relativity. WebAgain we typically ignore the momentum bit here because it's not needed for everyday objects that are much slower than light and have mass. For photons the opposite of that is true, they have no mass so we can …

In units with c = 1, we have m 2 = E 2 − p 2, where m is the invariant mass, E is the mass-energy, and p is the momentum. In terms of logical foundations, there is a variety of …

Web1 de fev. de 2016 · The use of words can make a lot of confusion. Unfortunately, the word "mass" has been used in two different ways in physics. One was the way Einstein used it in E=mc 2, where mass is really just the same thing as energy (E) but measured in different units.This is the same "m" that you multiply velocity by to find momentum (p), and thus …

Web28 de ago. de 2004 · 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.
