**11. What is the displacement of the wave at total interference in cm? Do NOT include units. Make the answer positive if it's up and negative if down.

**12. You are performing the Harmonics Lab on an apparatus in which the string length is 0.8 meters.  You find the first harmonic at 15 Hertz.  Fill in the chart to find the wavelength for the 4th harmonic. Do NOT include units
