The end of a tuning fork moves in simple harmonic motion described by the equation d = a sin (ot). If a tuning fork for the note D above middle C on an even-tempered scale has a frequency of 293.66 hertz (cycles per second), find. If the maximum displacement of the end of the tuning fork is 0.01 millimeter, determine the equation that describes the movement of the tuning fork. (Simplify your answer. Type an exact answer, using as needed.) Choose the equation that describes the movement of the tuning fork. Od=0.005 sin (587.32xt) O d = 0.005 sin (293.66mt) Od 0.01 sin (587.32xt) O d=0.005 sin 293.66 O Od 0.01 sin (293.66xt) d=0.01 sin 293.66
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.
