To determine a waves' frequency, you must know the
distance it travels.
number of oscillations in a given period of time.
distance between the crest and trough.
height of the wave.

The correct answer is number of oscillations in a given period of time

This is measured in what is called the Hertz measurement and the period of time is usually taken to be per second.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
