Unpolarized Light with Intensity I0 Is Incident on a Polarizer \circ

Question 62

Multiple Choice

Unpolarized light with intensity I0 is incident on a polarizer as shown.After passing through the first polarizer,the light has intensity I1.This light passes through a second polarizer that is rotated 45 \circ with respect to the first polarizer.The light now with intensity I2 passes through a third polarizer that is rotated 90 \circ with respect to the first polarizer.The intensity of light after the third polarizer is I3.Pick the one correct statement from the following statements.  Unpolarized light with intensity I<sub>0</sub> is incident on a polarizer as shown.After passing through the first polarizer,the light has intensity I<sub>1</sub>.This light passes through a second polarizer that is rotated 45<sup> \circ </sup> with respect to the first polarizer.The light now with intensity I<sub>2</sub> passes through a third polarizer that is rotated 90<sup> \circ </sup> with respect to the first polarizer.The intensity of light after the third polarizer is I<sub>3</sub>.Pick the one correct statement from the following statements.   A) I<sub>3</sub> = 0 B) I<sub>3</sub> = I<sub>0</sub>/8 C) I<sub>3</sub> = I<sub>0</sub>/3 D) I<sub>3</sub> = 2I<sub>0</sub> E) I<sub>3</sub> = I<sub>0</sub>/2


A) I3 = 0
B) I3 = I0/8
C) I3 = I0/3
D) I3 = 2I0
E) I3 = I0/2
