Answer:
0.29341
Explanation:
According to malus law , when the unpolarized light with intensity Io is incident on the first polarizer , the polarizer polarizes this incident light . The intensity becomes I²=1¹ cos²Q
I²= ( Io/2) cos²(Q²- Q¹)
= (Io/2) cos² ( 90°- 50°)
I²= ( lo/2) cos²40°
The intensity of light after it has passed through the Polaroid .
(Io/2) cos²40° = Io/2 ( 0.76660)²
= 0.293410
