Question

which wave has the lowest pitch? a they are the same i dont know b

Explanation:

Step1: Recall Pitch and Frequency

Pitch is related to frequency; lower pitch means lower frequency. Frequency is the number of waves (cycles) per unit time.

Step2: Compare Wave Frequencies

Wave A has more cycles (closer together), so higher frequency. Wave B has fewer cycles (more spread out), so lower frequency. Lower frequency means lower pitch.

Answer:

B. Wave B
