What is the frequency of the waves?

- math -
**Steve**, Thursday, December 8, 2011 at 11:04pmIt doesn't matter how long her boat is. The boat bobs up and down every 2 seconds. In that time, two wave fronts have passed. So, the frequency is 2waves/2sec = 1/sec = 1 Hz.

- math - my bad -

The two wave fronts means that the boat has bobbed twice by the time they have passed, but it only bobs once in 2 seconds. So, frequency is indeed 1/2 Hz
