Question

1. assuming that the diagram below illustrates two waves during the same period of time, what can be said about the frequency of wave 1 and wave 2?

wave 2 has a greater frequency than wave 1.
wave 1 and wave 2 have equal frequencies.
wave 1 has a greater frequency than wave 2.
wave 2 has a lower frequency than wave 1.

Explanation:

Frequency is the number of wave cycles per unit time. In the same time period, wave 2 has more cycles than wave 1. So wave 2 has a greater frequency.

Answer:

Wave 2 has a greater frequency than wave 1.
