Question

1 multiple choice 2 points use these graphs to answer the question. wave a wave b the two waves above are traveling at the same speed. which statement best describes the difference between the waves? wave a has a higher frequency than wave b. wave a has a lower frequency than wave b. wave a has a higher amplitude than wave b. wave a has a lower amplitude than wave b.

Explanation:

Step1: Understand frequency

Frequency is the number of waves passing a point in a given time. A wave with more cycles (peaks and troughs) in the same space has higher frequency.

Step2: Compare Wave A and Wave B

Wave B has more cycles (peaks and troughs) in the same horizontal space (same speed implies same time - space relation for comparison). So Wave A has lower frequency than Wave B.

Step3: Check amplitude

Amplitude is the maximum displacement from the rest position. Both waves have same maximum displacement (vertical distance from center line to peak). So amplitude is same.

Answer:

Wave A has a lower frequency than wave B.
