Question

diagram a (the left one)
diagram b (the right one)
which of the transverse waves has more frequency?
(wave a has 6 waves and wave b has 3 waves)

Explanation:

Step1: Recall Frequency Definition

Frequency ($f$) is the number of waves per unit time. If two waves travel the same distance (or in the same time frame), the one with more waves has higher frequency.

Step2: Compare Wave Counts

Wave A has 6 waves, Wave B has 3 waves. Since 6 > 3, Wave A has more waves in the same (implied) time/distance.

Step3: Determine Higher Frequency

From the definition, more waves mean higher frequency. So Wave A (Diagram A, the left one) has higher frequency.

Answer:

Diagram A (the left one)
