Can a photon be stationary
http://physics.bu.edu/~duffy/semester2/c35_compton.html Webmeans there is no photon in the first place! Conclusion: stationary electrons cannot absorb photons, but they can Compton scatter them. 6. Determine the maximum scattering angle in a Compton experiment for which the scattered photon can produce a positron-electron pair. Hint: twice the electron’s rest energy is required of

WebPhysics questions and answers. A photon, moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0210 nm. After the collision, the electron moves at an angle α below the +x-axis, while the photon moves at an angle θ = 80.3° above the +x-axis. (a) Calculate the speed of the electron (in ... WebJul 22, 2016 · A photon in the cavity can be simultaneously absorbed by both atoms at once, each atom taking half of the photon’s energy and both ending up in the excited state. The same holds, the researchers say, for three atoms with transition frequencies a third of that of the cavity resonance. The team found that, in effect, the system briefly ...
WebConvincing evidence that light is made up of particles (photons), and that photons have momentum, can be seen when a photon with energy hf collides with a stationary electron. Some of the energy and momentum is transferred to the electron (this is known as the Compton effect), but both energy and momentum are conserved in this elastic collision. WebApr 11, 2024 · A numerical simulation is a valuable tool since it allows the optimization of both time and the cost of experimental processes for time optimization and the cost of experimental processes. In addition, it will enable the interpretation of developed measurements in complex structures, the design and optimization of solar cells, and the …
WebFeb 27, 2024 · No, a photon can never move more slowly than the speed of light in vacuum, because as an elementary particle it is either in vacuum or interacting with another elementary particle or field. Now there are … WebMar 5, 2009 · Electrons will only be stationary at absolute zero, so they’re not really worth worrying about. An electron can only be stationary if its wavelength is infinity (ie. The electron hasn’t got a definable location). When considering conservation of energy and momentum in the collision between a photon and an electron (in Compton scattering for ...
