a. θ = 41. 4°
b. θ = 60°
c. θ = 75. 5°
d. θ = 90°
<h3>How to determine the angle</h3>
From the given information, we would be using the Malus' law
It is given as;
I = I0 cos²θ
Where I0 is the intensity of the polarized light after passing through P
a. To find the angle, compare with the given equation
I = (0.750)I0
I = I0 cos θ
then
cos θ = 0. 750
θ =
θ = 41. 4°
b. I = (0.500)I0
cos θ = 0. 500
θ =
θ = 60°
c. I = (0.250)I0
cos θ = 0. 250
θ =
θ = 75. 5°
d. I = 0
cos θ = 0
θ =
θ = 90°
