Question

A water wave passes by a floating leaf that is made to oscillate up and down two complete cycles each second, which means that the wave's frequency is

Answer 1

Answer:

2 Hz.

Explanation:

Frequency is simply defined as the number of appearances of a periodic event occurring per time. It is usually measured in cycles/second.

Now, in this question, we are told that there are 2 cycles for each second.

Thus, we can say that the frequency is 2 cycles/1 s = 2 Hz.
