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.

To measure the wavelength directly, we would need a group of instruments that measure the amplitude of the wave at the same time but at different locations. If we record the ground motion at a single location for a range of time, we can measure the time between peaks in the motion, which we call the wave period. Another important term is frequency, which is the inverse of the period, or one divided by the peak-to-peak time between wave crests. Waves are energy transmitting phenomena that have an amplitude and a wavelength. The upper panel shows a snapshot of the wave at a single time.
