Finely chop the onion and pour the salt and allspice over the onion, mixing them well. Meanwhile, soak the bulgur in warm water for 20 minutes and squeeze out the excess water, (or soak in the lemon juice for a crunchier and more lemony flavor).
(under construction). Wave period. Wave frequency is also related to another measurement called the wave period (T). The wave period is just how much time it takes for one cycle to pass and the units are always in terms of time.The faster a wave moves, its wave period becomes smaller.Instead of measuring in terms of a fixed time unit, the second, the wave period uses a fixed number of cycles, one cycle ...he wave period is just how much time it takes for one cycle to pass and the units are always in terms of time.

Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed. The period of a wave is the time it takes to complete one cycle. The frequency is just the opposite; it's the number of wave cycles that are completed in one second.Amplitude and wavelength are both measures of distance. The amplitude measures the height of the crest of the wave from the midline.he period of a wave is the time it takes to complete one cycle.
