Question

a student recorded data for two types of waves traveling at the same speed. their results are shown in the graphs below. which statement best describes the difference between the two waves? wave a has a higher frequency than wave b. wave a has a lower frequency than wave b. wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b.

Explanation:

Step1: Understand frequency and amplitude

Frequency is the number of waves per unit time. Amplitude is the maximum displacement from the rest position.

Step2: Analyze the graphs

Wave A has fewer cycles (waves) in the same space compared to Wave B. So Wave A has a lower frequency. The amplitude (height from rest) is the same for both waves.

Answer:

Wave A has a lower frequency than Wave B.
