A pool operator uses a motorized wave-generating paddle at one end of a leisure pool to produce waves.
The operator adjusted the settings so that the paddle pushed the water fewer times each minute.
What happened to the frequency of the waves produced?
Describe how the frequency of the waves in the pool can be measured experimentally by an observer standing at the side of the pool.
In a second test, the observer measured the frequency of the waves as 0.4 Hz.
Calculate the period of these waves.
Use the equation:
period=1frequency \text{period} = \frac{1}{\text{frequency}} period=frequency1Identify the correct unit for the period from the following options:
