Introduction: Transverse waves are waves that occur along a string. A transverse standing wave occurs when there is a good relationship of the frequency, length, and tension of the two waves moving back and forth along the string. Objective: Experiment 1: The objective of this experiment is to observe, using the eye, the frequency of multiple induced waves. Experiment 2: The objective of this experiment is to observe the frequency of waves by listening to their pitches. Method/Apparatus: Experiment 1: The apparatus used in this experiment is a light rubber band attached to a vibrator, which is powered by an oscillator.

Unformatted text preview: The tension in the rubber band is varied by hanging weights of different mass. Three waves are observed using three different weights. L is measured for each wave, and then the frequency is determined. Experiment 2: The apparatus used for this experiment is a sonometer with two piano wires stretched over it. One wire has a set tension and the other wire is tensioned by hanging weights of 5, 6, 7, and 8 kg. Tuning forks are hit and the length of the wire is adjusted to match the frequency of the tuning fork. The frequency is found using the adjusted length of the wire....
