3. You view light from a flashpoint through a Polaroid. Describe any intensity variation as the Polaroid is rotated. Explain your answer.

Describe any intensity variation as the flashlight is rotated.

4. Unpolarized light travels through two pieces of Polaroid as shown below.

When the two Polaroids are rotated to 0 degrees as shown, the transmitted intensity is I_0. What percentage of I_0 will be transmitted when the analyzer is rotated to 30 degrees? Show your calculation.

Solution Preview

Please see the attached file.

As the light from the flashlight is unpolarized the intensity is corresponding to oscillation of electromagnetic fields distributed uniformly in all direction in the plane perpendicular to the direction of light rays. After passing through the Polaroid only the oscillations parallel to the axis of Polaroid are passed through it and thus the transmitted light is polarized and there is decrease in intensity of transmitted light to half of its original value.

Now if the Polaroid is rotated, the axis of polarization rotates but ...
