Two straight metal wires connected to each other end-to-end. The first wire is made of magnesium and has a length of 13 m. The other wire is made of nickel and its length is 20 m. Both wires have the same cross-sectional diameter of 0.22 cm. They are stretched to a tension force of 1680 N. What time does it take for a transverse wave to travel through the entire system of two wires? The densities of magnesium and nickel are 1738 kg/m3 and 8908 kg/m3, respectively.
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.
