Explanation 1) Concept: We can apply Snell’slaw to find out the angle of refraction as the speed of incident and refracted wave is given. By applying definition of refractive index, we will get the ratio of speeds, and finally, we can find out the angle of refraction. 2) Formula: i) Index of refraction n = c v where c is speed of light in vacume and v is speed of light in medium ii) Snell’s law n 2 s i n θ 2 = n 1 s i n θ 1 3) Given: i) Angle of incidence θ 1 = 30 ° ii) v d = 4.0 m / s , speed of deep water wave iii) v s = 3.0 m / s , speed of shallow water wave 4) Calculations: a) We know that n 1 = c / v d and n 2 = c / v s Take ratio of n 1 and n 2 ; we get n 1 n 2

109 In Fig. 34-54, a fish watcher at point P watches a fish through a glass wall of a fish tank. The watcher is level with the fish; the index of re- fraction of the glass is 8/5, and that Watcher of the water is 4/3. The distances are di = 8.0 cm, dz = 3.0 cm, and dz = 6.8 cm. (a) To the fish, how far away does the watcher appear to be? (Hint: The watcher is the object. Light from that object passes through the wall's outside surface, which acts as a refracting sur- face. Find the image produced by that surface. Then treat that im- age as an object whose light passes through the wall's inside sur- face, which acts as another refracting surface.) (b) To the watcher, how far away does the fish appear to be? de D Wall Figure 34-54 Problem 109.

high-frequency sound waves exhibit less diffraction than low-frequency sound waves do. However, even high frequency sound waves exhibit much more diffraction under normal circumstances than do light waves that pass through the same opening. The highest frequency that a healthy ear can typically hear is 2.0 × 104 Hz. Assume that a sound wave with this frequency travels at 344 m/s and passes through a doorway that has a width of 0.95 m. (a) Determine the angle that locates the first minimum to either side of the central maximum in the diffraction pattern for the sound. (b) Suppose that yellow light (wavelength = 567 nm, in vacuum) passes through a doorway and that the first dark fringe in its diffraction pattern is located at the angle determined in part (a). How wide would this hypothetical doorway have to be?
