The speed of sound in dry air at 0C is 331.5 m/s and increases 0.6 m/s for each C rise in temperature, thus v(T)=(331.5+0.6T)m/s. Compare your value of the …

Lab Inquiry Activity
The speed of sound in air is 340 m s–1. (The speed of light is nearly a million times bigger than this, so you see the bat hit the ball more or less at the instant it occurs.) 2.

Physics Tutorial: The Speed of Sound
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.

Assume that the speed of sound in air is 340.0 m/s. How deep is the canyon at this location? The world speed record on water was set on October 9, 1978 by Ken Warby of Blowering Dam, Australia. If Ken drove his motorboat a distance of 1000 m in 7.045 s, how fast was his boat moving?

Discuss the differences between sound waves and light waves: Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

In a low density material, like air, sound travels much slower because the atoms are farther apart. The following activity with dominoes will illustrate this point. As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. Speed of sound through air (gas) = 343 m/s or 767 mph

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.

Therefore, the speed of sound in helium is about three times faster than the speed in air. In gases, the speed of sound depends on the temperature. In air, the speed increases approximately 0.60 m/s for each Celsius degree increase in temperature.
