Question

multiple choice question
how do wave a and wave b compare with each other?
wave b has greater amplitude and greater frequency.
wave b has greater amplitude and greater wavelength.
wave b has greater wavelength and lower frequency.
wave b has lower frequency and greater amplitude.

Explanation:

Step1: Analyze amplitude

Amplitude is the maximum displacement from the rest position. Wave B has a larger vertical displacement from the mid - line compared to Wave A, so Wave B has a greater amplitude.

Step2: Analyze frequency

Frequency is the number of complete waves per unit time. In the same horizontal space (assuming same time - interval represented horizontally), Wave B has more wave cycles (peaks and troughs) than Wave A. Since \(f=\frac{n}{t}\) (where \(n\) is the number of waves and \(t\) is time), and \(t\) is the same for the portion of the graph shown, Wave B has a greater frequency.

Answer:

Wave B has greater amplitude and greater frequency.
