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

Question 46

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
