In the figure shown below:the two photonsare shot from the light source and it reflects together from the bottom Glass top surface and both transmit through Glass A and then out of two, one photon reflects from top surface of the glass B and other transmits into Glass B and get reflected from bottom surface of the glass B and both they reach at C. What is the min and max probabilities of the photon reaching point C?

Explain all the steps that lead to calculations. (Only ANSWER IS NOT ACCEPTED). Draw the diagram yourself with points 1,2,3....n and show steps in each calculation leading to answer. If you show your work properly, partial credits would be given depending upon how much is correct, even if you get answer incorrectly.
