10. A stove is connected to a stove pipe of length L=3m. When the wind blows, the pipe sometimes "sings"(just like blowing across the top of a coke bottle). The fundamental frequency and lowest few overtones are usually heard. Assume the speed of sound to be 300 m/s. a) Assume that the pipe is "open" on one end and "closed" on the other. Draw adisplacement standing wave diagram for this case and determine the fundamental frequency of sound that is produced. b) Now suppose we open the closed end. Draw a displacement standing wave diagram for this case and determine the fundamental frequency of sound that is produced. c) The previous two problems dealt with two different configurations (open- closed and open-open). Which configuration and overtone produces a frequency of 150 Hz?
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
