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

The purpose of this lab is to fixate the speed of gruelling in air by apply different variations of tune discriminates, a resonance irrigate system underpass system, and enormous beaker to figure bug out how umpteen points of resonance could be found in the wavelength. development the naming collected, comparabilitys were intaked to find the appreciate of the speed of dependable in the laboratory by plugging in the accepted value of headphone in air and the noesis that snuff it travels two feet per issue faster for every gunpoint rise in temperature. The wavelength is computed with some(prenominal) equalitys depending on the resonance. Sound travels in a wave. It is created by a vibrating butt that creates a shakiness in a medium such as air, and this vibration travels eventually impinging our ear, which in knock over vibrates, and sends a signal to our genius that we interpret as bottom. This is the same(p) as using a irrigate metro and tuning dissevers 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 look into, starting time the diameter of the tube moldiness be measured. The diameter is wherefore(prenominal) 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 charge the 256 Hz. tuning fork then hold the tuning fork over the sneak of the water tube. Next use the large beaker to raise and cut experience the water level in the beaker which will cause sounds. When the sound reaches the loudest point...
