Answer Wiki. There is really only one measure of time, and that is hours/minutes/seconds/days/weeks/months/years. Then you have derivations of these including Lunar years, light years, periods between full moons, days (between sun rises), but they all come back to the traditional time of hours/minutes/seconds.

Amplitude is a measure of how big the wave is. 1  Imagine a wave in the ocean. 2  It could be a little ripple or a giant tsunami. 3  What you are actually seeing are waves with different amplitudes. 4  They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different.ince frequency and period are exact inverses of each other, there is a very basic pair of formulas you can use to calculate one if you know the otherâ¦. It is very easy to do these calculations on calculators using the x -1 button. Example 1: The period of a pendulum is 4.5s.
