In each of the following cases, initially vertically polarized light enters the polarizing apparatus with the same initial intensity. Which polarizing apparatuses will cause the light to exit with the largest intensity, 90° from its initial polarization?
a) A single polarizing filter, oriented 90° from the vertical
b) Two polarizing filters, the first 45° from the vertical and the second 90° from the vertical
c) Two polarizing filters, the first 60° from the vertical and the second 90° from the vertical
d) Two polarizing filters, the first 30° from the vertical and the second 90° from the vertical.

- Multiple ChoiceUnpolarized light strikes a polarizing filter. It then passes through a second polarizer. The axis of the second polarizer is tilted from the axis of the first. If the intensity of light emerging from the second polarizer is . what intensity does the light have as it strikes the first polarizer?527views

Unpolarized light with intensity of 6 W/m2 is incident on a polarizer. If the polarizer's transmission axis is at an angle of 45° above the horizontal, draw a diagram of this system and find the intensity of transmitted light.

The axis of the first filter makes an angle of 60.0° with the vertical, and the axis of the second filter is horizontal. What is the intensity of the light after it has passed through the second filter?646views
- Textbook QuestionA beam of unpolarized light of intensity I0 passes through a series of ideal polarizing filters with their polarizing axes turned to various angles as shown in Fig. E33.27. (b) If we remove the middle filter, what will be the light intensity at point C?740views
- Textbook QuestionLight of original intensity I0 passes through two ideal polarizing filters having their polarizing axes oriented as shown in Fig. E33.28. You want to adjust the angle f so that the intensity at point P is equal to I0/10. (a) If the original light is unpolarized, what should Φ be?424views
