Unpolarized light of intensity I, is sent through three polarizing sheets as shown in the figure. The polarizing direction of the first sheet is vertical. The polarizing direction of the second sheet is rotated counterclockwise by 30 degrees with respect to the vertical. The polarizing direction of the third sheet is rotated counterclockwise by 60 degrees with respect to the vertical. What is the emergent intensity I ?

The group that worked at your station in the preceding lab left a copy of one of the plots they made during the lab. If the plot looks like the image shown below, how many polarizers were used to make the plot? (Assume that the unpolarized light of 20 lux falls on the first polarizer, and if more than two polarizers are used, assume only the second polarizer rotates.) Intensity 10 4 Angle 45 135 180 225 270 315 360 06 Select one: 1 3 2
