a] Ratio of intensity I/i0 = 1/2*cos^2 theta
0.46 = 0.5 * (cos theta)^2
cos theta = sqrt(0.46/0.5) = 0.959
angle theta = arccos 0.959
= 16.46 degree
b] percentage of light = 46% * cos (90 - 16.46 degree )^2
= 46* [sin 16.46 degree]^2
= 3.693 %

When a beam of light passes through a pair of polarizing filters (polarizer and analyzer), the intensity of the transmitted light is a maximum when the transmission axes of the polarizer and analyzer are parallel to each other (θ = 0° or θ= 180°) and zero when the axes are perpendicular to each other (θ = 90°). For any value of theta between 0° and 90° the transmitted intensity is given by I = Ii cos2(θ) where Ii is the...
Unpolarized light with an intensity of 10.8 W/m2 is incident on a pair of polarizers. The transmission axis of the first polarizer makes an angle 39.3° to the vertical, while the transmission axis of the second polarizer is vertical. (b) Suppose the second polarizer is rotated so that its transmission axis is horizontal. What is the intensity of the light after it passes through both polarizers?
GOAL Understand how polarizing materials affect light intensity. Unpolarized light is incident upon three polarizers. The first polarizer has a vertical transmission axis, the second has a transmission axis rotated 30.0 degree with respect to the first, and the third has a transmission axis rotated 75.0 degree relative to the first. If the initial light intensity of the beam is I_b, calculate the light intensity after the beam passes through the second polarizer and the third polarizer. After the beam...
The drawing shows three polarizer/analyzer pairs. The incident light beam for each pair is unpolarized and has the same average intensity of 46 W/m2. Find the average intensity of the transmitted beam for each of the three cases (A, B, and C) shown in the drawing. A: ST = B: ST = C: ST =
Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer makes an angle of 40.0° with the axis of the polarizer. (b) What fraction of the original light is absorbed by the analyzer (the second polarizer)? (that is find (I adsorbed/ I incident on the first polarizer))

Unpolarized light of intensity 100 W/m2 is incident on polarizer #1. After passing through polarizer #1, the light then passes through polarizer #2 whose transmission axis is at 20 degrees to that of polarizer #1. What is the intensity of the light transmitted through polarizer #2? (in units of W/m2)
