Q1

For the next two questions, consider the case with two beam-splitters present in the experiment, and no phase shifter present.

Compare the experimental results for classical particles and for electromagnetic waves, and list the ways in which they are similar or different. Explain any differences between the two in terms of how each behaves when encountering the second beam-splitter.

Q2

How do the experimental results for single photons compare with the results for classical particles and for electromagnetic waves? How does the behavior of a single photon at the second beam-splitter compare with classical particles and with electromagnetic waves?

Explanation / Answer

Q1. For two beam splitters in case of classical particles

when the particle arrives at splitter one, it either moves in 1st direction or the second direction ( only one of those)

lets assume the second splitter is in direction 2

so there is a 50 percent chance that this particle will arrive at splitter 2 from where it has 25 percent chance to go to location 2 and 3

hence the particle has 50 percent changce to go to location 1, and 25 percent chance each to reach location 2 and 3

for the EM wave, the first beam splitter spl;its the beam into two beams of half intensities, hence location 1 recieves 50 percent of the beam intensity and splitter 2 recieves 50 percent of the beam intensity

after leaving splitter 2, the location 2 recievesx 25 percent of the original intensity and so does location 3

hence the dfifference between the classical and the EM wave will be the fact that in classical particle the particvle will be present only at one of the locations with the given probabilities whereas in EM wave there will be expected intensity distribution at the three locations but the intensity distribution will be jkust as it was for the probability distribution in the classical particvle case

Q2. experimental results for single photons will be the same for the classical particle both for the first and the second splitter, and the results for the EM wave will be similiar to using multiple photons and counting the number of photons at different locations as relative intensity distributions of the EM wave
