How long does it take the sound waves to reach 5 meters? Using the above information, calculate the speed of sound in m/s. Remember, speed is the amount of distance traveled PER second. Increase the frequency to 900Hz. How long does it take the sound waves to reach 5 meters? What is the speed of the wave now? Decrease the frequency to 200Hz.

The speed of sound in an ideal gas S is given by the equation12. S = √ RT/M, (eq. 1) where is the adiabatic constant, T is the absolute temperature in kelvins, M is the molecular weight of the gas, and R is the gas constant per mole, 8.314 J/mol K. The average molecular weight of dry air is 28.95 gm/mol, and the adiabatic constant = 1.4, so ...

Compared to most objects, sound waves travel very fast – fast enough that measuring the speed of sound accurately is a technical challenge. One method is to time an echo. For example, if you were in an open field with a large building 100 meters away, you could start a stopwatch when a loud noise was made and stop it when you heard the echo.
