6 In Fig. 33-29, unpolarized light issent into a system of five polarizingsheets. Their polarizing directions,-xmeasured counterclockwise from thepositive direction of the y axis, are thefollowing: sheet 1, 35°; sheet 2, 0°;sheet 3, 0°; sheet 4, 110°; sheet 5, 45°.Sheet 3 is then rotated 180° counter-clockwise about the light ray. Duringthat rotation, at what angles (mea-sured counterclockwise from the yaxis) is the transmission of lightthrough the system eliminated?Figure 33-29 Question 6.
