Unformatted text preview: A tuning fork is held above the open end of the tube, causing the water level to change based on the frequency of the sound from the tuning fork. The change in water level is used to measure L, and then λ and the speed of sound can be found. Experiment 2: The apparatus used in this experiment is a speaker mounted to the end of a pipe with a length L attached to an oscillator. A microphone is moved across the tube forming sound waves. The distance between the nodal points, l, can be measured and then λ can be calculated. From this, the speed of sound can be determined....
