A long tube contains air pressure of 1 atm. and temp of 77degrees C. the tube is open at one end, and closed by a movable piston on the other end. A tunning fork is near the open end and is vibrating at a frequency of 500Hz. Reasonance is produced when the piston is set at 18, 55.5, and 93 cm. From these measurements what is the velocity of sound in air at 77degC.
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.

I'm getting 375m/s and I don't think it is right because I was a little confused on my process. I appreciate your help with this problem. Thank you.
