WebPhoton momentum is given by the equation: Entering the given photon wavelength yields Solution for (b) Since this momentum is indeed small, we will use the classical expression $latex \boldsymbol {p = mv} $ to find the velocity of an electron with this momentum. WebApr 11, 2024 · Strong interactions of single photons are generally difficult to realize. To tackle this problem, several recent studies [71-75] came up with an alternative strategy: two-particle dynamics with interactions in a 1D space have an equivalent mapping to single-photon dynamics in a 2D space, similar to the method discussed in Section 2.5. Here, an ...

Webphotons are so weird and i love it the only possible way for something to travel at the speed of light is for it to have absolutely no mass, yet photons have a finite quantity in this universe, so how tf do they not have any mass?? they have energy and momentum, but no mass?? 14 Apr 2024 20:14:14 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.

WebSep 22, 2014 · Because photons have energy -- and, as Einstein taught us, energy is equal to the mass of a body, multiplied by the speed of light squared. How can photons have energy if they have no mass? (One imagines Einstein thinking about photons re: mass and shrugging, hoping that nobody noticed the discrepancy.) WebApr 1, 2014 · Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. Now there is an interesting …

WebAnswer (1 of 32): The classic definition for momentum has always been in terms of particle velocity ‘v’ and particle mass ‘m’. But the definition of momentum became ambiguous when Louis de Broglie came up with an equivalent QM description of momentum in terms of photon-wavelength ‘λ’. The equiva... Now, based on classical Newtonian mechanics and the formula p=mv, a photon would not have any momentum as it has no mass. So, Newtonian mechanics must be incorrect in this case.
