Concept explainers

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.

Question

100%

The physics of wind instruments is based on the concept of standing waves.
When the player blows into the mouthpiece, the column of air inside the
instrument vibrates, and standing waves are produced. Although the acoustics
of wind instruments is complicated, a simple description in terms of open and
closed tubes can help in understanding the physical phenomena related to
these instruments. For example, a flute can be described as an open-open
pipe because a flutist covers the mouthpiece of the flute only partially.
Meanwhile, a clarinet can be described as an open-closed pipe because the
mouthpiece of the clarinet is almost completely closed by the reed.
Throughout the problem, take the speed of sound in air to be 343 m/s.
