Chapter 17: Q9. (page 482)

FIGURE Q17.9 shows the circular waves emitted by two in-phase sources. Are a, b, and c points of maximum constructive interference, maximum destructive interference, or in between?

Short Answer

Expert verified

a: Maximum Constructive interference

b: In between.

c: Maximum Destructive interference

Step by step solution

01

Given information.

Two coherent sources emit circular waves. At 3 mentioned points we have to figure out the type of interference.

02

Part a:

Amplitude of both waves meet here, therefore this point will show maximum constructive interference.

03

Part b:

At this location we have amplitude of the wave from source 2 and some in between value of wave from source 1. Therefore this point will show in between interference.

04

Part c:

This point contributes to trough of both the waves and therefore will show maximum destructive interference.

Standing waves on a 1.0-m-long string that is fixed at both ends are seen at successive frequencies of 36 Hz and 48 Hz. a. What are the fundamental frequency and the wave speed? b. Draw the standing-wave pattern when the string oscillates at 48 Hz.

Noise-canceling headphones are an application of destructive

interference. Each side of the headphones uses a microphone to

pick up noise, delays it slightly, then rebroadcasts the noise next

to your ear where it can interfere with the incoming sound wave

of the noise. Suppose you are sitting 1.8 m from an annoying,

110 Hz buzzing sound. What is the minimum headphone delay, in

ms, that will cancel this noise?

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?

Two identical loudspeakers separated by distance ∆xeach

emit sound waves of wavelength λ and amplitude a along the

x-axis. What is the minimum value of the ratio ∆xλ for which

the amplitude of their superposition is also a?

In music, two notes are said to be an octave apart when one note is exactly twice the frequency of the other. Suppose you have a guitar string playing frequency f0. To increase the frequency by an octave, to 2f0, by what factor would you have to (a) increase the tension or (b) decrease the length?
