Suppose you watch a leaf bobbing up and down as ripples pass it by in a pond. You notice that it does two full up and down bobs each second. Which statement is true of the ripples on the pond?
A)They have a wavelength of two cycles per second.
B)We can calculate the wavelength of the ripples from their frequency.
C)They have a frequency of 2 hertz.
D)They have a frequency of 4 hertz.

The leaf is bobbing up and down with a frequency of 2 hertz, meaning it completes two full cycles (up and down) in one second. This frequency corresponds to the frequency of the ripples on the pond. The wavelength of the ripples cannot be determined from the given information.
