The accepted speed of sound at atmospheric pressure and 0 °C is 331.5 m/s. The speed of sound increases 0.607 m/s for every °C. Calculate the speed of sound at the temperature of your room and compare your measured value to the accepted value. Extensions 1. Repeat this experiment, but collect data with a tube with an open end.

speed of sound in air. Theory There are a variety of wave types. Sound is a longitudinal wave requiring a medium in which to propagate. A longitudinal wave is one in which objects oscillate in the same direction the wave propagates. The speed of sound depends on proper-ties of the medium such as bulk modulus, density, and temperature. The speed ...

The equation for speed is distance traveled/time to travel that distance. Using the example length of 100 m (328 ft), if the runner took 10 seconds to run that distance, the runner's speed would be 100 m (328 ft) divided by 10, or 10 m/sec (32.8 feet per second). We will be measuring the speed of sound in air using a balloon. The time is

speed of sound in air is referred to as Mach 1 by aerospace physics. Although "the speed of sound" is commonly used to refer air, the speed of sound can be measured in virtually any substance. Sound travels faster in liquids and non-porous solids (5,120 m/s in iron) than it does in air,

Depending on what the propagation medium is, the sound speed can change with frequency. Non-Dispersive Medium – Sound speed is independent of frequency, therefore the speed of energy transport and sound propagation are the same. Air is a non-dispersive medium. Dispersive Medium – Sound speed is a function of frequency. The spatial and temporal

4. Speed of Sound The speed of sound, c, in a substance is the speed at which infinitesimal pressure disturbances propagate through the surrounding substance. To understand how the speed of sound depends on the substance properties, let’s examine the following model. Consider a wave moving at velocity, c, through a stagnant fluid. Across the ...

Velocity of Sound The apparatus for measuring the speed of sound is a vertical cylinder of gas. The length of the column of gas is adjusted by changing the height of a metal reservoir of oil. A loudspeaker is attached to the top of the cylinder, and it generates sound from an electrical audio oscillator.
