What is the result of shining light through two polarizing filters whose transmission axes are perpendicular to each other?

When light passes through two polarizing filters with their transmission axes perpendicular to each other, no light is transmitted through the second filter. The first polarizer only allows light waves aligned with its transmission axis to pass through, while the second polarizer blocks all light waves that are not aligned with its own axis. As a result, the intensity of the transmitted light is effectively zero.
