3. Start the program and allow your object to make a few waves. Pause the program. Using the provided scale, measure the wavelength of the waves both in front of and behind of the plane. Use these wavelengths and the speed of the waves to calculate the frequency of the waves (frequency = velocity of waves/wavelength of waves) 4. Increase the speed of plane by 10 m/s and a pausing it once it reaches the middle of your display. Record your observations and calculations. Complete the table below by increasing the speed of the plane in increments of 10 m/s until you reached 90 m/s. Speed of plane (m/s) Wavelength in front of Frequency in front of Wavelength behind the Frequency behind the plane (m) plane (Hz) plane (m) plane (Hz) 0 10 20 30
