1. A traveling wave has displacement given by y(x, t) = (2.0cm) X cos(2Πx 4Πt, where x is measured in cm and t in s.
a. Draw a snapshot graph of this wave at t = 0 s.
b. On the same set of axes, use a dotted line to show the snapshot graph of the wave at t = 1/8 s.
C. What is the speed of the wave?
2. Figure 15.17 is a snapshot graph of a wave at t = 0 s. What are the amplitude, wavelength, and frequency of this wave? 3. Figure 15.18 is a history graph at x = 0 m of a wave moving to the right at 2 m/s. What are the amplitude, frequency, and wavelength of this wave?
