Questions

Alice stands up straight while she performs experiments with photons and filters. In each of the experiments, vertical refers to the way Alice is standing, and horizontal refers to the line of the floor:

1. In the first experiment, 1,000 vertically polarized photons hit a vertically polarized filter. How many of the photons get through the filter?
2. In the next experiment, 1,000 vertically polarized photons hit a horizontally polarized filter. How many of the photons get through the filter?
3. In Alice’s next experiment, 1,000 vertically polarized photons hit a diagonally polarized filter. The ones that make it through hit another filter that’s diagonally polarized in the same direction as the first filter. Assuming that 500 photons made it through the first filter, how many of them make it through the second filter?
4. In another experiment, 1,000 vertically polarized photons hit a diagonally polarized filter. The ones that make it through hit another...
