glass air Incident ray Figure 1 On figure 1 above, a light ray in air (n = 1.0) is incident on thick glass sheet (n = 1.5). Use a protractor and a ruler to accurately draw the ray of light as it travels in the glass. Draw and label the normal and the incident and refracted angles (and state their measured values).

Sections 9.6 and 9.7 deal with the phenomena of dispersion and its applications to atmospheric optics. One such application is the explanation of rainbows. Develop a concept map that you could use to teach a friend or family member about the formation and basic characteristics of rainbows. Your map should include links to the fundamental physical processes of reflection, refraction, and dispersion and should distinguish between primary and secondary rainbows. It should also indicate the conditions that must be satisfied to observe rainbows.
A water fountain is at the center of a circular pool as shown in Figure P1.59. A student walks around the pool and measures its circumference C. Next, he stands at the edge of the pool and uses a protractor to measure the angle of elevation of his sightline to the top of the water jet. How high is the fountain?
You stand in a flat meadow and observe two cows (Fig. P1.73). Cow A is due north of you and 15.0 m from your position. Clow B is 25.0111 from your position. From your point of view, the angle between cow A and cow H is 20.0, with cow B appearing to the right of cow A. (a) How far apart are cow A and cow B? (b) Consider the view seen by cow A. According to this cow, what is the angle between you and cow B? (c) Consider the view seen by cow B. According to this cow, what is the angle between you and cow A? Hint: What does the situation look like to a hummingbird hovering above the meadow? (d) Two stars in the sky appear to be 20.0 apart. Star A is 15.0 ly from the Earth, and star B. appearing to the right of star A. is 25.0 ly from the Earth. To an inhabitant of a planet orbiting star A. what is the angle in the sky between star B and our Sun? Figure P1.73 Your view of two cows in a meadow. Cow A U due north of you. You must rotate your eyes through an angle of 20.0 to look from cow A to cow B.
(i) An object is placed at a position p > f from a concave mirror as shown in Figure CQ9.10a, where f is the focal length of the mirror. In such a situation, an image is formed at a distance q from the mirror, as we discuss in Chapter 26. The distances are related by the mirror equation: In a finite time interval, the object is moved to the right to a position at the focal point F of the mirror. Show that the image of the object moves at a speed greater than the speed of light. (ii) A laser pointer is suspended in a horizontal plane and set into rapid rotation as shown in Figure CQ9.10b. Show that the spot of light it produces on a distant screen can move across the screen at a speed greater than the speed of light. (If you carry out this experiment, make sure the direct laser light cannot enter a person’s eyes.) (iii) Argue that the experiments in parts (i) and (ii) do not invalidate the principle that no material, no energy, and no information can move faster than light moves in a vacuum. Figure CQ9.10
