Question

which statement can be made about waves a and b? wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b. wave a has a lower frequency than wave b. wave a has a higher frequency than wave b.

Explanation:

Step1: Recall wave - property definitions

Amplitude is the maximum displacement from the rest position. Frequency is the number of waves passing a point in a given time.

Step2: Compare amplitudes

The amplitudes of Wave A and Wave B seem to be the same as the maximum displacements look equal.

Step3: Compare frequencies

Wave B has more wave cycles in the same length compared to Wave A, so Wave B has a higher frequency and Wave A has a lower frequency.

Answer:

Wave A has a lower frequency than Wave B.
