A beam of gamma rays from a distant galaxy is observed through two polarizing filters whose transmission axis is at a 45 degree angle relative to each other here on earth.

a) How fast are the gamma rays propagating after encountering the filters?

b) What is the intensity of the output beam relative to the intensity of the gamma rays prior to passing through the polarizers?
