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 2, 2010 · p = 0 (because you have to add two equal and opposite momentum) so: E^2 = (mc^2)^2 --> m = E/c^2. That is: the system of the two photons have mass. Invalid application. Each photon has no rest mass and energy equal to (pc)^2. With 2 photons in opposite directions the energy is (pc)^2 + (-pc)^2 = 2 (pc)^2. Jun 30, 2008.

The force on the sail depends on the sail area, the reflectivity, the angle of incidence, and the ... WebJun 11, 2013 · 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.

WebThe momentum of a photon is easy, if you know its frequency. Since the photon is massless, the magnitude of its momentum is equal to to its energy divided by c, the speed of light. The direction is of course the direction the photon is going. WebAnswer (1 of 4): Light is described as a type of electromagnetic wave. The electromagnetic field is described by Maxwell's equations, which predict that the speed c with which electromagnetic waves (such as light) propagate through the vacuum is related to the electric constant and the magnetic c...
