Question

1. What is the intensity of the light once it has passed through the polarizer?
2. What is the angle of polarization of the light once it has passed through the polarizer? Measure the angle relative to the vertical. (Use deg for degrees.) clock wise or counter clockwise?

2. What is the angle of polarization of the light once it has passed through the polarizer? Measure the angle relative to the vertical. (Use deg for degrees.) clockwise or counter clockwise?

Explanation / Answer

1)

for the unpolarized light

initial intensity , I0 = 3.5 W/m^2

intensity of light after passing through the pokarizer , I1 = 0.5 * I0

intensity of light after passing through the pokarizer , I1 = 0.5 * 3.5

intensity of light after passing through the pokarizer , I1 = 1.75 W/m^2

intensity of light after passing through the pokarizer is 1.75 W/m^2

2)
the light will be polarized along the axis of polarizer

hence , the angle of polarization of light is 59 degree clockwise relative to vertical
