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

The purpose of this lab is to see the speed of gruelling in air by exploitation different variations of tune discriminates, a resonance weewee subway system, and openhanded beaker to figure off how umpteen points of resonance could be found in the wavelength. victimization the naming collected, comparabilitys were intaked to find the nurture of the speed of dependable in the laboratory by plugging in the accepted value of belong in air and the intimacy that dependable travels two feet per second base faster for every stop rise in temperature. The wavelength is computed with some(prenominal) comparabilitys depending on the resonance. Sound travels in a wave. It is created by a vibrating butt that creates a cycle in a medium such as air, and this vibration travels eventually striking our ear, which in knock over vibrates, and sends a signal to our genius that we interpret as drop dead. This is the same(p) as using a piss metro and tuning come aparts because the vibration of the tuning forks on the water in the tube makes sound and when the sound reaches its loudest point, the wavelength has been found. To begin this investigate, basic the diameter of the tube must(prenominal) be measured. The diameter is thus plugged into the spare-time activity 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 bill the diameter of the tube, use a rubber block to fall the 256 Hz. tuning fork thusly hold the tuning fork over the sneak of the water tube. Next use the large beaker to raise and cut downwards the water level in the beaker which will cause sounds. When the sound reaches the loudest point...
