Question
The graph below shows the depth of water in a harbor as a wave passes through.
From the graph, measure the wavelength of the wave.
▶️Answer/Explanation
Ans: Measuring peak to peak gives 3.5 – 1 = 2.5 m
Question
Determine the amplitude of the wave.
▶️Answer/Explanation
Ans: \(\frac{3.4-2.8}{2}=0.3m\)
Question
The speed of the waves is 1.4 m s–1. Calculate how long it takes a wave to pass a given point.
▶️Answer/Explanation
Ans: \(f=\frac{1.4}{2.5}=0.56 Hz; T = \frac{1}{0.56}=1.79s\)
