72 Two sinusoidal 120 Hz
waves, of the same frequency
and amplitude, are to be sent in
the positive direction of an x axis
that is directed along a cord un-
der tension. The waves can be

sent in phase, or they can be
phase-shifted. Figure 16-47
shows the amplitude y' of the re-
sulting wave versus the distance of the shift (how far one wave is
shifted from the other wave). The scale of the vertical axis is set
by y', = 6.0 mm. If the equations for the two waves are of the
form y(x, t) = ym sin(kx + wt), what are (a) ym, (b) k, (c) w, and
(d) the correct choice of sign in front of w?

66 Figure 16-44 shows the dis-
placement y versus time t of the
point on a string at x= 0, as a
wave passes through that point.
The scale of the y axis is set by
y, = 6.0 mm. The wave is given
by y(x, t) = ym sin(kx – wt + 4).
What is 4? (Caution: A calculator
does not always give the proper
inverse trig function, so check your answer by substituting it and an
assumed value of w into y(x, 1) and then plotting the function.)

- Suppose a spherical loudspeaker emits sound isotropically at 10 W into a room with completely absorbent walls, floor, and ceiling (an anechoic chamber).

(b) What is the ratio of the wave amplitude at d= 4.0 m to that at d= 3.0 m?arrow_forward95 A continuous traveling wave with amplitude A is incident on a boundary. The continuous reflection, with a smaller amplitude B, travels back through the incoming wave. The resulting interference pattern is displayed in Fig. 16-51. The standing wave ratio is defined to be A + B А — В SWR The reflection coefficient R is the ratio of the power of the reflected wave to the Ana Amin Am max ах power of the incoming wave and is thus proportional to the ratio (BIA). What is the SWR for (a) total reflection and (b) no reflection? (c) For SWR = 1.50, what is R expressed as a percentage? Figure 16-51 Problem 95.arrow_forwardThe intensity of a sound source is described by an inverse-square law only if the source is very small (a point source) and only if the waves can travel unimpeded in all directions. For an extended source or in a situation where obstacles absorb or reflect the waves, the intensity at distance r can often be expressed as I = cPsource/r, where c is a constant and the exponent î, which would be 2 for an ideal spherical wave, depends on the situation. In one such situation, you use a sound meter to measure the sound intensity level at different distances from a source, acquiring the following data: Distance, r (m) 1 3 10 30 100 Intensity level, ß (dB) 100 93 85 78 70 Part A You want to determine the exponent a for this sound source by graphing the data. Select the appropriate variables to graph on each axis that will produce a straight- line graph with either a slope or intercept that will allow you to determine x.
