The height of the speaker stack was designed to be equal to the wavelength of the sound wave produced by the lowest string. If the frequency of this harmonic vibration is 31 Hz and the length of the string is 0.89m (89cm), what is the speed of the ave on the string? If the density of the string is 0.0657 kg/m what is the Tension of the string? If the speed of sound is 343 m/s what will be the wavelength of the sound made by the first harmonic vibration (hint: this is the height of the tallest stack of speakers)
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.
