A 15-cm-deep opaque container is empty except for a single coin resting on its bottom surface. When looking into the container at a viewing angle of 50o relative to the vertical side of the container, you see nothing on the bottom. When the container is filled with water, you see the coin (from the same viewing angle) on the bottom of, and just beyond, the side of the container. How far is the coin from the side of the container?
Answer to relevant QuestionsTwo upright plane mirrors touch along one edge, where their planes make an angle of α. A beam of light is directed onto one of the mirrors at an angle of incidence of β(β < α) and is reflected onto the other mirror. (a) ...The index of refraction of crown glass is 1.515 for red light and 1.523 for blue light. (a) If light of both colors is incident on crown glass from air, the blue color will be refracted (1) more, (2) less, or (3) the same ...The critical angle between two materials is 43o. If the angle of incidence is twice the angle of refraction, what are the angles of incidence and refraction? How would you use a converging lens as a magnifying glass? Can you do the same with a diverging lens? Draw ray diagrams that show how three images of an object are formed in two plane mirrors at right angles, as shown in Fig. 23.27a. Figure 23.27b shows a similar situation from a different point of view that gives four ...
