A computer monitor (idle) displays a pulse signal as illustrated in the figure below. Suppose the ordinate axis represents the displacement in arbitrary units and the abscissa is the time t whose divisions smaller ones are in units of 1 s. The pulse is the result of the superposition of two sound waves at the point of the computer's sensor. a wave is generated by a tuning fork A at rest that emits at 436 Hz and the other wave is by a tuning fork B that moves at Speed 2.4 m/s directly towards the sound sensor. Take the speed of sound in air to be 341 m/s. Use the diagram above to find the value of the frequency that tuning fork B would emit at rest.
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.
