Chapter 17: Q. 73 (page 487)

A flutist assembles her flute in a room where the speed of

sound is 342 m/s. When she plays the note A, it is in perfect tune

with a 440 Hz tuning fork. After a few minutes, the air inside her

flute has warmed to where the speed of sound is 346 m/s.

a. How many beats per second will she hear if she now plays the

note A as the tuning fork is sounded?

The solution also provides a detailed description of

A flautist assembles her flute in a room where the speed of

sound is 342 m/s.

Step by step solution

01

Description of the speed of sound 

The speed of sound describes the area it travels per second

A steel wire is used to stretch the spring of FIGURE P17.42. An oscillating magnetic field drives the steel wire back and forth. A standing wave with three antinodes is created when the spring is stretched 8.0 cm. What stretch of the spring produces a standing wave with two antinodes?

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.50 m. If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x = 0.90 m.

a. What is the frequency of the sound? Assume vsound = 340 m/s.

b. What is the phase difference between the speakers?
