A man is playing the lowest note on a 5 string bass guitar, which has a frequency of f= 30 s, and it corresponds to the lowest frequency standing wave on the heaviest string on the guitar. a) If the wavelength of this standing wave on the guitar string is 1 = 2 m, then how long is the portion of the string that is free to move? b) What is the wave speed of traveling waves on this guitar string? c) This 30 Hz tone is being amplified by a powerful loudspeaker. What is the wavelength of the sound wave emitted by the speaker? You may approximate the speed of sound as 300 m/s. d) What is the frequency heard by a woman driving at a speed of 30 m/s away from the guitar player?

A tuning fork generates sound waves with a frequency of 246 Hz. The waves travel in opposite directions along a hallway, are reflected by end walls, and return. The hallway is 47.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s.
A 0.80-m-long tube is opened at both ends. The air temperature is 26°C. The air in the tube is oscillated using a speaker attached to a signal generator. What are the wavelengths and frequencies of first two modes of sound waves that resonate in the tube?
Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
An entrepreneur decides to invent and market a device that will fool the Doppler radar units used to detect cars that are speeding. The device would be placed at the very front of the car and would detect the radar signal, determine its frequency, and transmit back its own radar signal that would make the radar unit register a legal speed. What would the frequency of the "fake'' signal have 10 be in comparison to the original? If a second unit were designed to be placed at the back end of the car, what would be different about the frequency it would have to use compared to that used by the unit at the from?
