HOMEWORK HELP THANKS!!!
Q1
For the next three questions, consider the case with two beam-splitters and the phase shift inserted into the lower path.
As the phase shifter is varied, how is the behavior of single photons similar to electromagnetic waves? How is their behavior different from electromagnetic waves?
Q2
Is the behavior of a single photon at the first beam-splitter changed by the presence of a second beam-splitter? Does its behavior at the first beam-splitter depend on whether or not the phase shifter is present?
Q3
Explain how the phase shifter is able to affect the behavior of a single photon at the second beam-splitter.
Q4
Summarize your findings from the inteferometer questions above by characterizing how photons behave in these experiments: In what sense do they behave like classical particles? In what sense do they behave like classical waves? Was there a case where the photons acted only like classical particles; or acted just like electromagnetic waves? Or must photons be something different to both electromagnetic waves and classical particles?
Explanation / Answer
1. Single photon beam has the same sensation as that of electromagmetic waves, like the electric and magnetic field are perpendicular to the direction of propagation but the difference in the phase is not same as that of electromagnetic field.
2. Yes, the behavior of a single photon at the first beam-splitter changed by the presence of a second beam-splitter because of the spliting of waves in the presence of other, and this behaviour depends on the phase shifter as that decides the difference in the spliiting of waves.
3. Phase shifter creates a spliiting in the electric and magnetic field of the wave and causes a change in the direction of these fields with respect to the propagation of wave. This depends upon the value of phase shifter as the value of phase is decided by the the phase shifter.
4. Photons are waves having some classical properties, and they behave as classical particles when the velocity of wave is very less compared to the speed of light. In that case also, the wave nature dominates the classical behaviour so they must not be different from that of EM waves.
