Unformatted text preview: standing waves formed on the string produced a pattern, leading to the deduction of a relationship between order of harmonic and frequency. The velocity of the wave was also determined, and from this, the frequency and tension. For the Speed of Sound in Air, a tuning fork was struck and held near the opening of a long marked cylinder with a tube extending from the bottom into a reservoir of water. As the longitudinal sound waves hit the water, the level was adjusted up and down to find the length for which a resonance occurs. Standing waves occur when the length L (distance from the top), is so that the reflected wave is a maximum when it reaches the top of the tube. The length of the tube was the n=2 wavelength. A relationship was found between the resonance and the length L....
