I need to understand how I get the experimental determined speed of sound if my calculated wavelength is 8cm ? So I can be able to do on my own. I know 331.4 + 0.6 × tcm My room temperature calculation is 21 degree Celsius
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.

We have the measured length. We will use it to calculate the wavelength by given formula in table.
Eg :
measured length = 2 cm
4L = 2 x 4 cm = 8 cm = 0.08 m
Now we will use the second formula:
v= f
speed of sound (v)= 0.08 x 2048 = 163.84 m/s
