In the application shown below, sound from the speaker divides into two equal parts that recombine at the receiver. Note that the path length of sound may be varied in the top part by means of the sliding section. The speed of sound is 343 m/s and the frequency of sound emitted by the speaker is 839 Hz. A rectangular tube where the top section is comprised of a sliding U-shaped part has an opening at the center of the left and right sides of the tube. The bottom half of the tube has a path length of r1 between the openings and the top half of the tube has a path length of r2 between the openings. A speaker is pointed at the opening on the left side and shows sound waves entering the tube going through both paths towards the right opening. A human ear labeled Receiver is next to the right opening. (a) If constructive interference occurs at a particular location of the sliding section, by what minimum amount (in m) should the slider be moved upward so that the destructive interference occurs instead?  m (b) What minimum distance (in m) from the original position of the sliding section will again result in constructive interference?  m

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.
