The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.nswer: 0.0195 sec. Here is an example of a problem with a lot of extraneous information. The period is simply the reciprocal of the frequency. In this case, the period is 1/(51.2 Hz) which is 0.0195 seconds.
The speed (or sometimes you might see it called velocity) of a wave, v, is how far the wave travels in a certain time. Wave speed is measured in metres per second (m/s). All the electromagnetic waves travel at 300,000,000 metres per second (3 x 10 8 m/s).he speed (or sometimes you might see it called velocity) of a wave, v, is how far the wave travels in a certain time.
