The graphs below represent the motion wave traveling down a string. The top graph represents the motion of one part of the string as it changes over time. The bottom graph represents a \'snapshot\' in time of the profile of the string, showing the displacement of the string as a function of distance along the string. you will be measuring some values off the graphs and you will be using simple calculations to get other values. Pay close attention to the correct answer the computer gives you. Please use THIS number in subsequent calculations. What is the wavelength of the wave? What is the period of the wave? What is the frequency of the wave? What is the amplitude of the wave? What is the speed of the wave?

Solution

a) From Graph 2, wavelength = 2 * (8 - 3) = 10m
b) From Graph 1, Time period of the wave (T) = 2 * (0.5 - 0.21) = 2 * 0.29 = 0.58s
c) Frequency = 1/T = 1.72 Hz
d) From Graph 2, Amplitude = 0.6cm
e) Speed of Wave,c = wavelength/time = 10/0.58 = 17.2 m/s
