Sound is a longitudinal wave requiring a medium in which to propagate. The purpose of this lab experiment is to determine the relationship between the speed, frequency and wavelength of sound waves by measuring each of these properties. In principle one could measure the speed of sound by timing how long Compared to most things you study in the physics lab, sound waves travel very fast. Repeat the experiment several times and take the average value of the time intervals recorded to calculate the average speed of sound. Sound travels to a distant building and SPEED OF SOUND Objective To determine the speed of sound in air by means of a resonating air column at room temperature. Objective The objective of this experiment is to measure the speed of sound in air. Standing on a hill some distance away from the cannon someone measured the time between the flash of the cannon and the following boom.

The speed of light in vacuum and Cavendish’s torsion balance experiment for G have been my favorites so far.

The sound SOUND EXPERIMENT TO FIND THE SPEED OF SOUND Sound travels much more slowly than light in the air. The other end will be closed, sealed off by water in the tube. Resonances are obtained in a straight pipe partially inserted into a bucket of water. You must design an experiment which allows you to measure the speed of sound waves in air. Compare your experimental value to the true value. For example, at Temp = 18 C, the speed of sound is 342. The objective of this task is to measure the speed of sound using the ‘time of flight’ technique. With a sound card and two microphones it is relatively easy to measure the speed of sound.

We can use this to measure how quickly the sound does travel. The relationship between these quantities is: v = fl where v = velocity of sound propagation f = frequency l = wavelength This lab is designed to take place over two weeks and focuses on measuring the speed of waves. The speed of sound in the rod is calculated using the length of the rod and the frequency of the vibrations.
