Chapter 2: Q3DQ (page 537)

Would you expect the pitch (or frequency) of an organ pipe to increase or decrease with increasing temperature? Explain.

Short Answer

Expert verified

The frequency of the organ pipe increases with the increase in the temperature.

Step by step solution

01

Write the given data:

The organ pipe with increased and decreased temperature.

02

Determine the concept

Consider the relation between the wavelength and the frequency of the wave as:

λ=vsf

03

Determine the explanation for the given question

Consider the frequency of the organ pipe increases as the temperature increases this is because the sound travels in the air as the molecules hit each other. With the higher temperature the molecules hits each other with the more energy.

Therefore, the frequency of the organ pipe increases with the increase in the temperature.

Two loudspeakers, A and B (Fig. E16.35), are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speakers emit sound waves that travel directly from the speaker to point Q. What is the lowest frequency for which (a) constructive interference occurs at point Q; (b) destructive interference occurs at point Q?

An organ pipe has two successive harmonics with frequencies 1372 and 1764 Hz. (a) Is this an open or a stopped pipe? Explain. (b) What two harmonics are these? (c) What is the length of the pipe?

Consider a sound wave in air that has displacement amplitude 0.0200 mm. Calculate the pressure amplitude for frequencies of (a) 150 Hz; (b) 1500 Hz; (c) 15,000 Hz. In each case compare the result to the pain threshold, which is 30 Pa.

BIO The Human Voice. The human vocal tract is a pipe that extends about 17 cm from the lips to the vocal folds (also called “vocal cords”) near the middle of your throat. The vocal folds behave rather like the reed of a clarinet, and the vocal tract acts like a stopped pipe. Estimate the first three standing-wave frequencies of the vocal tract. Use v = 344 m/s. (The answers are only an estimate, since the position of lips and tongue affects the motion of air in the vocal tract.)

A railroad train is traveling at 30.0 m/s in still air. The frequency of the note emitted by the train whistle is 352 Hz. What frequency is heard by a passenger on a train moving in the opposite direction to the first at 18.0 m/s and (a) approaching the first and (b) receding from the first?
