Problem: Unpolarized light of 120 W/m2 intensity passes through two polarizing filters. First, it passes through a polarizing filter with its axis aligned vertically, then it passes through a polarizing filter with its axis aligned horizontally. (a) What is the intensity of the light after it passed through the filters? (b) If a third polarizing filter was placed between the original two, with its axis aligned at 45o from the vertical, what would the intensity of the light be after it passed through all three filters?

🤓 Based on our data, we think this question is relevant for Professor Hoeger's class at UCSD.
