The graph shows the displacement of a wave as a function of position (the snapshot graph) at time t=0. The vertical axis is displacement in cm and the horizontal axis is position in meters. If the wave is travelling to the right at 1.28 m/s, what is the period of this wave, in seconds?

Transcribed Image Text:The graph illustrates the displacement of a wave as a function of position (the snapshot graph) at time t=0. The vertical axis represents displacement in centimeters, while the horizontal axis shows position in meters.
**Description of Graph:**
- The wave is sinusoidal, oscillating between -4 cm and 4 cm.
- The horizontal axis ranges from 0 to 15 meters, with periodic peaks and troughs.
**Questions:**
1. If the wave travels to the right at a speed of 1.28 m/s, what is the period of this wave in seconds?
2. For the previous question, assume the same snapshot graph depicts a wave with a period of 8.4 seconds, traveling to the left at a potentially different velocity than before. If the graph indicates the height of water in a wave and a duck is floating at the position x=5 meters, what is the maximum vertical speed of the duck during the oscillation?
