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.

WebApr 29, 2003 · I have read in a book, to simply think of many sources one in front of the other systematically firing photons(or bullets) sequencially. The bullets will always have a specific velocity but a frequency shift will exist when compared to one source stationnary emiting photons (or bullets) at a same time interval. WebA photon is a type of elementary particle that primarily acts as a carrier of energy. An electron is a subatomic particle that is present in all atoms. A photon has no charge. It possesses a negative charge of magnitude 1.62 × 10 −19 coulomb. It has no rest mass. An electron has a mass of 9.19 × 10 -31 kilograms. gestational diabetes reasons for induction

Does energy have mass? ResearchGate

WebSep 28, 2015 · E relates to the ability of the photon to perform work on matter. Its ability to do work on matter is proportional to its frequency. Energy has units of mass x distance^2/time^2 and it is defined as the ability to do work. Energy is not only defined in relation to mass - it only has meaning in relation to matter/mass. Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy. Photon energy can be expressed using any unit of energy. Among the units commonly used to d… WebThe rest mass is always the same for the same type of particle.

WebIf photons have mass then magnetic fields at large distances will behave differently than if photons don't have mass. The experiements did not see any of the effects that photons with mass would have, so the scientists involved were able to put a limit on how much mass a photon could have based on how good the instrument was. WebIt is now a well-established fact that photons do have momentum. In fact, photon momentum is suggested by the photoelectric effect, where photons knock electrons out of a substance. Figure 29.14 shows macroscopic evidence of photon momentum.

WebAnd if the electron were at the third energy level, or the second excited state, the electron could absorb a one eV photon. Those are the only photons that this atom will be seen to absorb. 2.5eV photons will pass straight through, five eV photons will pass straight through, 6.3eV photons will pas straight through. http://physics.bu.edu/~duffy/py106/PhotoelectricEffect.html

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 additional effect contained in the general equation. If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0). But an object with zero energy and ...
