- Directions: On the space provided before each number, write T if the statement is true and F if the statement is false. _1. In a pendulum, the restoring force comes from the tension in the string. _2. Vibration is just mechanical oscillation. _3. The wavelength of a transverse wave is equal to the period of its corresponding sine or cosine graph. _4. The "w" in periodic motion refers to angular velocity. 5. Amplitude is unaffected when there is resonance.q3Sound waves move in air at a speed of 340 m/s. You play a piano note with a frequency of 220 Hz.
