Final answer:
To test the wave speed hypothesis, you can design an experiment using rubber tubing to create waves in water. Measure the frequency by timing how long it takes to move the hand up and down. Measure the wavelength using a meter stick, and use the wave velocity equation to determine consistency.
Step-by-step explanation:
This experiment requires two people. Start by measuring the frequency of the wave pattern by timing how long it takes one person to move their hand up and down one full time using rubber tubing. It's recommended to time this ten times and then divide by ten to reduce error. Next, measure the wavelength of the standing wave by using a meter stick to measure the distance between two nodes and multiplying by two. Repeat this process for standing wave patterns of different wavelengths. Finally, use the wave velocity equation to determine if the wave velocity is consistent based on the gathered data. Note that there may be some error in the experiment due to inaccuracies in the wavelength and/or frequency measurements.
