Analysis/ Background: For this problem we have two identical aluminum rods,each of these rods is then fixed at one end, and is caused to vibrate in its fundamental harmonic. They do so simultaneously, and so you hear one tone of the single frequency. Now one of the rods is heated, so it's temperature is higher than the other rod. Once again both rods are caused to vibrate simultaneously at their fundamental frequency. And the Question is what is it that we hear? Additional Information: Unheated rod vibration emits a sound with frequency 880 Hz The heated rod has been raided by 60°C hotter than the previous rod ( this does not change the speed of the transverse wave in the rod)
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.
