Could someone help me asnwer these queations about polarization?
Polarization2.jpg Chapter 11: Light Waves 3. Below are a pair of Polarolds with polarization axes at 30 to each other. Carefully draw vectors and Polarization appropriate components (as In Question 2} to show the vector that anverges al e. The amplitude of a light wave has magnitude and direction, and can be represented by a vector. Polarized light vibrates in a single direction and is represented by a single vector. To the left the single vector represents vertically polarized light. The vibrations of non-polarized light are equal In an directions. There are as many vertical components as horizontal components. The pair of perpendicular vectors to the right represents non-polarized light. B 1. In the sketch below non-polarized light from a lashlight strikes a pair of Polarold filters. (b) NON-POLARIZED LIGHT VIBRATES IN ALL DIRECTIONS HORIZONTAL AND VERTICAL COMPONENTS a. The amount of light that gets through the Polaroids at 30', compared to the amount that gets VERTICAL COMPONENT PASSES though the 45 Polaroids Is VERTICAL COMPONENT THROUGH FIRST POLARIZER DOES NOT PASS THROUGH (less) {more) (the same) ... AND THE SECOND THIS SECOND POLARIZER 4. Figure 11.43 In your textbook shows the smile of Ludmile Hewitt emerging through three Polarolds. Use vector diagrams to complete steps b through a below to show how light gets through the three- Polarold system. B, Light is transmitled by a pair of Polaroids when their axes are (alloned) (crossed at right angles) and light is blocked when their axes are (aligned] [crossed at right angles) b. Transmitted light is polarized In & direction (a) ( * ) (f) (the same as) [different than) the polarization axis of the filter. 5. A novel use of polarization is shown below. How do the polarized side windows in these next.ic. each other houses provide privacy for the occupants? (Who can see what?) 2. Consider the transmission of light through a pair of Polarolds with polarization axes al 45' to each ciher. Although in practice the Polerolds are ons atop the other, we show them spread out side by side below. From left to right: (a) Nonpolarized light is represented by its horizontal and vertical components. (b) These components strike filter A. (c) The vertical component is transmitted, and () tells upon flier B. This vertical component is not aligned with the polarization axis of filter B, bu: it has a component that is - component f. (e) which is transmitted. 10 (a) . . . . SIDE WINDOWS POLARIZED GLASS a. The amount of light that gets through b. The component perpendicular to t that Filler B, compared to the amount thai falls on Filter B is gets through Finer A Is (also transmitted) (absorbed] (more) (less) (the same)
