7 Problem #7A stretched string that lies along the x-axis has a sinusoidal traveling wave propa-gating along it. Figure 7 shows the history plots for two points, one at x = 0m andthe other at x0.09m.1. What is the amplitude of the wave?2. What is the period of the wave?3. The points x = 0m and x =the wavelength and the speed of the wave if the wave is moving towards positivex values.0.09m are within one wavelength apart. Determine4. Determine the wavelength and the speed of the wave if the wave is movingtowards negative x values.5. If you were not told that the two points were within one wavelength apart,would it be possible to determine the exact wavelengths in parts 3 and 4?
