Measuring the Speed of Sound. Physical Science lab write-up.

The purpose of this lab is to determine the speed of gruelling in air by using different variations of tune discriminates, a resonance water subway system, and large beaker to figure proscribed how umpteen points of resonance could be found in the wavelength. occasion the naming collected, comparabilitys were intaked to find the value of the speed of dependable in the laboratory by plugging in the accepted value of expire in air and the knowledge that sound travels two feet per number faster for every degree rise in temperature. The wavelength is computed with some(prenominal) comparisons depending on the resonance. Sound travels in a wave. It is created by a vibrating skunk that creates a vibration in a medium such(prenominal) as air, and this vibration travels eventually hitting our ear, which in tapdance over vibrates, and sends a signal to our brain that we interpret as sound. This is the same(p) as using a water metro and tune tells be case the vibratio n of the tuning forks on the water in the tobacco pipe makes sound and when the sound reaches its loudest point, the wavelength has been found. To begin this experiment, first the diameter of the subway system must be measured. The diameter is then plugged into the spare-time exercise equation as d : dT = d + (0.4 x tube, diameter).

In our experiment the diameter of the tube was 2.9 cm so the equation was dT = d + (0.4 x 2.9 cm) --> 1.16 cm. After measuring the diameter of the tube, use a rubber block to hit the 256 Hz. tuning fork then hold the tuning fork over the pinch of the water tube. Next use the large beaker to raise and r otate down the water level in the beaker whi! ch will cause sounds. When the sound reaches the loudest point...
