Polarization Filters

25 - EM waves - Polarization

Unpolarized light strikes a polarizing filter. It then passes through a second polarizer. The axis of the second polarizer is tilted <math display=“inline”><mrow><mn>45</mn><mo>&#x00B0;</mo></mrow></math> from the axis of the first. If the intensity of light emerging from the second polarizer is <math display=“inline”><mrow><mn>45</mn><msup><mrow><mtext>&#x00A0;</mtext><mtext>W/m</mtext></mrow><mn>2</mn></msup></mrow></math>. what intensity does the light have as it strikes the first polarizer?

Polarized Light and Polarized Filters

Polarization of Light: circularly polarized, linearly polarized, unpolarized light.

Vertically polarized light of intensity <math display=“inline”><mrow><mn>24</mn><msup><mrow><mtext>&#x00A0;</mtext><mtext>W/m</mtext></mrow><mn>2</mn></msup></mrow></math> strikes a polarizing filter with its axis tilted <math display=“inline”><mrow><mn>30</mn><mo>&#x00B0;</mo></mrow></math> clockwise from vertical. What is the intensity of the transmitted light?

Polarization of Electromagnetic Waves — Lesson 5

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

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?&nbsp;a) A single polarizing filter, oriented 90° from the vertical&nbsp;b) Two polarizing filters, the first 45° from the vertical and the second 90° from the vertical&nbsp;c) Two polarizing filters, the first 60° from the vertical and the second 90° from the vertical&nbsp;d) Two polarizing filters, the first 30° from the vertical and the second 90° from the vertical.
