Chapter 17: Q. 74 (page 487)

You have two small, identical boxes that generate 440 Hz

notes. While holding one, you drop the other from a 20-m-high

balcony. How many beats will you hear before the falling box hits

the ground? You can ignore air resistance.

Short Answer

Expert verified

The solution gives a detailed description of air resistance and

two small, identical boxes that generate 440 Hz

notes

Step by step solution

01

Description of resistance

Resistance is a measure of opposite current flow in an electrical circuits

02

Step 2; Description on the frequency, time and period

Provided solutions

The integral beat of frequency

N=∫0ffB(t)tdt

The heard frequency will bef-f01+vxv=f0vv+vs

as per the strategic box the frequency difference is ;

fb=fo-fo-fovv+vs=(1-vv+vs)fo

03

The integral part becomes

dudt=g→dt=dug∫duu=lnu+CN=440.(222-3439.8.2+34329.82ln343+9.8.2343

A flute player hears four beats per second when she compares her note to a 523 Hz tuning fork (the note C). She can match the frequency of the tuning fork by pulling out the “tuning joint” to lengthen her flute slightly. What was her initial frequency?

Ultrasound has many medical applications, one of which is to monitor fetal heartbeats by reflecting ultrasound off a fetus in the womb.

a. Consider an object moving at speed votoward an at-rest source that is emitting sound waves of frequency f0. Show that the reflected wave (i.e., the echo) that returns to the source has a Doppler-shifted frequencyfecho=v+v0v−v0f0

A 1.0-m-tall vertical tube is filled with 20∘C water. A tuning fork vibrating at 580 Hz is held just over the top of the tube as the water is slowly drained from the bottom. At what water heights, measured from the bottom of the tube, will there be a standing wave in the tube above the water?

FIGURE Q17.8 is a snapshot graph of two plane waves passing

through a region of space. Each wave has a 2.0 mm amplitude

and the same wavelength. What is the net displacement of the

medium at points a, b, and c?

Two loudspeakers emit sound waves of the same frequency along the x-axis. The amplitude of each wave is a. The sound intensity is minimum when speaker 2 is 10 cm behind speaker 1. The intensity increases as speaker 2 is moved forward and first reaches maximum, with amplitude 2a, when it is 30 cm in front of speaker 1. What is

a. The wavelength of the sound?

b. The phase difference between the two loudspeakers?

c. The amplitude of the sound (as a multiple of a) if the speakers

are placed side by side?
