Problem 8: A mass M = 2.3 kg is hanging from a long string of length L = 16.2 m and total mass m = 15 kg. A student gives the mass a quick horizontal shake to set up a wave which travels upwards along the string. Part (a) What is the speed of the wave at the bottom of the string, in meters per second? Numeric A numeric value is expected and not an expression. Vh = Part (b) Express the tension of the chain at a height y above the bottom in terms of M, m, and g. Expression: T(y) = Select from the variables below to write your expression. Note that all variables may not be required. a, ß, 0, a, d, g, h, j, k, L, m, M, P, t, y Part (c) What is the speed of the wave, in meters per second, at the top of the string? Numeric A numeric value is expected and not an expression. Vt = Part (d) How long does it take, in seconds, for the wave to travel up the string? Numeric : Anumeric value is expected and not an expression. %3D
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.
