How is the frequency of a wave measured?
- the number of seconds the signal takes to complete one up and down cycle
- the number of times the signal makes one complete up and down cycle in 1 second
- the number of times the signal makes one complete up and down cycle in 2 seconds
- the number of seconds the signal takes to complete two up and down cycles
