A beam of initially unpolarized light of intensity 723 W/m^2 passes through a series of polarizing filters, each one s axis aligned at a 17.9- degree angle with respect to the previous filter s axis. The beam of light emerging from the final filter in the series has an intensity of 220.1 W/m^2. How many polarizing filters did the beam pass through?
