Question

Armand is monitoring a large sealed tank by way of a sensor that records the liquid level over time on a graph. He looks at the graph and claims that the sensor indicates there are waves in the liquid in the tank.

In the space provided, answer each of the following.

Part A: Explain how Armand knows that there is a wave in the tank.
Part B: Find the amplitude, in centimeters (cm), and frequency, in number of waves every second/cycle per second (Hz), of the wave.

Answer 1

Part A: Armand most likely looked at the graph that the liquid sensor sends information too.

I don’t have an answer for part b, sorry
