The Beam Splitter, a Half Silvered Mirror

For every photon that you send through a beam splitter, it's got a 50% chance of either going through or being reflected. Some photons have enough energy to go through, some by chance, and some will bounce off rit so firing a photon will result in 50 % going through the half silvered mirror and 50%. So far makes perfect sense. All right, clear. Now i'm going to take a secondhalf silvered mirror. K, a second beamSplitter, and put it there. Let's see what happens. We've got five and four out of nine. That's close to 50 50. If we got exactly 50 50, that would be a bit strange
