Chapter 2: Q1DQ (page 537)

When sound travels from air into water, does the frequency of the wave change? The speed? The wavelength? Explain your reasoning.

Short Answer

Expert verified

The frequency will be constant, while the speed and wavelength of the sound will change.

Step by step solution

01

Write the given data:

Given that the sound travels from the air to water.

02

Determine the concept

The number of wave cycles in a second is termed as frequency. The wave sped is the distance travelled by the wave in unit time, the wavelength of the wave is the distance between the two crest and the troughs of the wave.

03

Determine if the frequency, speed and the wavelength of the wave changes

Note the frequency of wave depends on its source so it will not change with the medium.

The speed of the wave depend on the properties of the material and is the product of the wavelength and the frequency of the wave. Since, water and air have different properties so the speed of the wave will change.

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

λ=vsf

Note that the speed will change with the wavelength of the sound.

Therefore, the frequency will be constant, while the speed and wavelength of the sound will change.

Two identical loudspeakers are located at points A and B, 2.00 m apart. The loudspeakers are driven by the same amplifier and produce sound waves with a frequency of 784 Hz. Take the speed of sound in air to be 344 m/s. A small microphone is moved out from point Balong a line perpendicular to the line connecting Aand B(line BC in Fig. P16.65). (a) At what distances from Bwill there be destructiveinterference? (b) At what distances from Bwill there be constructiveinterference? (c) If the frequency is made low enough, there will be no positions along the line BCat which destructive interference occurs. How low must the frequency be for this to be the case?

What is the purpose of the frets on a guitar? In terms of the frequency of the vibration of the strings, explain their use.

Two loudspeakers, Aand B, are driven by the same amplifier and emit sinusoidal waves in phase. The frequency of the waves emitted by each speaker is 172 Hz. You are 8.00​ mfrom role="math" localid="1655809995061" A. What is the closest you can be to Band be at a point of destructive interference?

One end of a horizontal rope is attached to a prong of another end passes over a pulley and supports a 1.50-kg mass. The linear mass density of the rope is 0.0480 kg/m. (a) What is the speed of a transverse wave on the rope? (b) What is the wavelength? (c) How would you answer to parts (a) and (b) change if the mass were increased to 3.00 kg?

In some applications of ultrasound, such as its use on cranial tissues, large reflections from the surrounding bones can produce standing waves. This is of concern because the large pressure amplitude in an antinode can damage tissues. For a frequency of 1.00 MHz , what is the distance between antinodes in tissue?
