Two organ pipes, open at one end but closed at the other, are each long. One is now lengthened by . Find the beat frequency that they produce when playing together in their fundamentals.
The beat frequency came out to be .

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 , what is the distance between antinodes in tissue?
You have a stopped pipe of adjustable length close to a taut 62.0-cm, 7.25-g wire under a tension of 4110 N. You want to adjust the length of the pipe so that, when it produces sound at its fundamental frequency, this sound causes the wire to vibrate in its second overtone with very large amplitude. How long should the pipe be?
A sinusoidal wave can be described by a cosine function, which is negative just as often as positive. So why isn’t the average power delivered by this wave zero?
In a transverse wave on a string, the motion of the string is perpendicular to the length of the string. How, then, is it possible for energy to move along the length of the string?
A sound wave in air at 20°C has a frequency of 320 Hz and a displacement amplitude of For this sound wave calculate the (a) pressure amplitude (in Pa); (b) intensity (c) sound intensity level (in decibels).
