Can a photon be stationary
WebAug 28, 2014 · In any case, a emission of a photon would entail energy being lost from the system. Since the electron is in a 'stable orbit' this has to be prohibited or the orbit would decay with each emission ... WebMay 7, 2015 · The energy of the photon is found by computing the difference in the energies of the fourth (n=4) and second (n=2) levels E = -13.6/4 2 - (-13.6/2 2) E = -0.85 + 3.40 E = 2.55 eV 3. Now use the above expression to find the energy of the photon released when a free electron is captured to the 2nd level.

WebBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr explained the hydrogen spectrum in terms of electrons absorbing and … 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 ...
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. WebAs for the relation of photon numbers to classical fields, I can suggest an analogy that you could study that might be easier to picture. Look at the wave functions that represent …

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.

Physicists irreversibly split photons by freezing them in Bose-Einstein condensate. Summary: They cool photons down to a Bose-Einstein condensate, which causes the light to collect in optical ‘valleys’ from which it can no longer return. ... Can you have a stationary photon?
