The period of a wave is the time it takes for one complete cycle or pulse to occur. In this case, six pulses are generated every 0.200 seconds. To find the period, we divide the total time by the number of pulses:
Period = Total time / Number of pulses
Period = 0.200 seconds / 6 pulses
Period ≈ 0.0333 seconds per pulse
The frequency of a wave is the number of cycles or pulses that occur in one second. It is the reciprocal of the period:
Frequency = 1 / Period
Frequency ≈ 1 / 0.0333 seconds per pulse
Frequency ≈ 30 pulses per second
So, the period of the wave is approximately 0.0333 seconds per pulse, and the frequency of the wave is approximately 30 pulses per second.
