Sound is a moving density wave. it can travel through basically any normal form of matter. What does this mean density wave? well what this means is that you have a domino effect bascally, one air molecule is moving, it bumps its neighbor then its naghborr bumps its other neighbor and it keeps going until the sound energy is dispersed or turned into heat.
The wave speed of sound depends upon how close the molecules are to each other. It is like plucking a string. if you pull it tight the string vibrates much more frequently than if you hold it very loosely. In air, the molicules are quite far apart from each other, so the sound travels a lot slower but in a metallic material, the atoms are shoulder to shoulder and the speed of sound is about 1300 mph were as in the air it's about 300 mph.

Answer:
8.40 m/s
Explanation:
Slope of the plot is 0.119
Slope of a plot is given by the change in y direction divided by the change in x direction
Here, the y axis represents inverse wavelength and the x axis represents frequency.
f = Frequency (Hz, assumed)
v = Phase velocity (m/s, assumed)
λ = Wavelength (m, assumed)
So, slope
Now,
The speed of sound travelling in the tube is 8.40 m/s
