Speed of Sound Formula: Definition, Equations and Examples
Speed of sound in air is given by the equation where r is the gas constant, M is the molar mass of air and T is the Kelvin temperature. Use your measured value of speed of sound and the room temperature to obtain a value for the speed of sound in air at (a) 0oC, (b) at 100oC.

The speed of sound in a gas in inversely proportional to the square root of the molecular weight of the gas through which the sound is passing the speed of sound will be greater in moist air. This is because the molecular weight of water is less than that of dry air. At 20oC 100 kPa and 0% humidity the speed of sound is 343.4 m/s.

speed of sound: v = 332 m/s + 0.6 m/s (T), where v is the speed v = of sound. Go back and input this value in both data tables. Determining the wavelength of the resonant waves. Now that you know the frequency of the resonant waves AND the speed of sound, determine the wavelength of the resonant waves using the wave speed equation.

If you know the frequency of a sound source you can then calculate the speed of sound using the equation below. Speed of Sound = frequency x wavelength. You are familiar with the concept of resonance, but perhaps never knew what it was called. For example, you may have heard a vase across the room rattle when just one note on a piano was played.
