Period = 1 / frequency
Period = 1/frequency = 1/500 = 0.002 second = 2 milliseconds
Assuming that seconds refers to the period, the frequency is the reciprocal (1 / period in seconds). The height of the wave is irrelevant in this case.
Wave frequency f, and period of wave T are inverses, related by fT=1.
frequency = (wave speed)/(wavelength) frequency = 1/(period)
