MY NOTESASK YOUR TEACHERPRACTICE ANOTHERPolarizing windows, filters, etc. are often used to reduce the amount of light that enters the lens of a camera or into a room or acar. A library atrium has an overhead skylight that lets in too much light during the day which heats up the interior of the libraryfar too much. The building engineer installs new double paned polarizing sky lights to reduce the intensity. If sunlight, which isunpolarized, has an average intensity of 1280 W/m2 what angle should the polarizing axis of the second pane of the window makewith the polarizing axis of the first pane of the window in order to reduce the intensity of the sunlight to 35% of the originalvalue?Additional MaterialsO ReadingA Tutorial

Light is prepared so that it is polarized at 15.4 degrees with an intensity of 0.553 W/m2. The light passes through a polarizer oriented to pass polarization at an angle of 65.2 degrees and then through a second polarizer oriented to pass polarization at 90.0 degrees. What is the intensity in W/m2 of the light after passing through the second polarizer? (Enter answer with 3 digits right of the decimal.
You and your friend Bruce are experimenting with a red lamp shade and blue lamp shade. You place lamp shades individually over a 120-W light bulb. Assume that the light radiates from the lamps uniformly and 9.5% of their power is converted to light. (a) What is the average intensity of the light at 1.6 m from the red (1 = 710 nm) lamp shade? W/m2 (b) Is the average intensity of the blue (1 = 480 nm) lamp shade at 1.8 m greater than, less than, or equal to the intensity calculated in part (a)? greater than less than O equal to
4. An industrial laser is used to burn a hole through a piece of metal. The average intensity of the light is 1.20 x 10° W/m2. What is the rms value of the electric field in the electromagnetic wave emitted by the laser? N/C
A wave is passing through two polarizers. It is an unpolarized electromagnetic wave, and it initially has a max electric field magnitude of 20000N/C. The 1st polarizer, polarizes at an angle of 20 degrees vertical. The 2nd polarizer, polarizes at an angle of 30 degrees horizontal. What would be the intensity of a light wave that passes through the two polarizers?
Experiments show that the ground spider Drassodes cupreus uses one of its several pairs of eyes as a polarization detector In fact, the two eyes in this pair have polarization directions that are at right angles to one another Suppose linearly polarized light with an intensity of 775 W/m² shines from the sky onto the spider and that the intensity transmitted by one of the polarizing eyes is 774 W/m². For this eye, what is the angle between the polarization direction of the eye and the polarization direction of the incident light?
Vertically polarized light of intensity lo is incident on a polarizer whose transmission axis is at an angle of 70° with the vertical. If the intensity of the transmitted light is measured to be 0.34W/m², the intensity lo of the incident light is O 1.71 W/m2 O 0.99 W/m² O 0.43 W/m2 O 2.91 W/m²
Unpolarized light passes through three polarizing filters. The first filter has its transmission axis parallel to the z direction, the second has its transmission axis at an angle of 30.0° from the z direction, and the third has its transmission axis at an angle of 60.0° from the z direction. If the light that emerges from the third filter has an intensity of 587.0 W/m², what is the original intensity of the light? (Assume both angles are measured in the same direction from the +z axis.) W/m2
Unpolarized light of intensity lo =208 W/m² passes through a first polarizer with its polarizing axis in the vertical position and then through a second polarizer oriented an angle of 84 degrees with the first polarizer. What is the intensity of the light emerging from the second polarizer? Enter you answer in W/m2 with one decimal place precision.
