1. Three ideal polarizing filters are aligned in succession in the path of a horizontal beam of unpolarized light of intensity 50 W/m2 . The first and last filters each have their transmission axis vertical; the other filter's axis is 36.9 degrees from the horizontal. What is the intensity of the light that has passed through all three filters?

2. There are two parallel slits 0.10 A?µm wide, 0.050 mm apart, in one wall of Pierre's tent; outside there is a strong colored light source (main wavelength 500 nm). How far apart are the centers of adjacent bright bands on the opposite wall, 2.4 m away?

3. An oil slick on top of a puddle is strongly reflecting yellow light from directly above it. If the principal component of the reflected light is at 576 nm and the index of refraction of the oil is 1.4. How thick is the oil layer, if there is one smaller thickness value that would give a similar strong reflection?
