Instructor Justin Tyme is about to demonstrate beat frequency when he notices that Prionus (Pri) Parer has given him three tuning forks with a note that says one fork is brand new and the frequency of 256 Hz is correct for it and that the beat frequencies between pairs are 1,3 and 5 Hz. All three are stamped 256 Hz and two of them are obviously old and abused. Justin should expect to measure beat frequencies for [ Select ] pairs of forks to determine [Select ] the actual frequencies of each of the three forks. 1 3 The pairs he should use are [ Select ]
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.

Beats are formed when two sound waves having equal amplitudes and slightly different frequencies superimposes. If the resonating frequencies of two sound sources are known, then beat frequency (
