1 Place the bulgur in a bowl, and cover with water by 1/2 inch. 2  Soak for 20 minutes, until slightly softened. 3  Drain through a cheesecloth-lined strainer, and press the bulgur against the strainer to squeeze out excess water.
Amplitude. Amplitude is a measurement of the vertical distance of the wave from the average. The wave axis is the average height of the wave over one cycle, and is usually considered to be zero. Heights above and below the average are given positive and negative values, respectively. The wave shape shown below is called a sine wave. The maximum and minimum amplitudes of this sine wave are the heights measured from the wave axis (white line) to the top of the wave peak and bottom of the wave trough.
Amplitude is a measure of how big the wave is. 1  Imagine a wave in the ocean. 2  What you are actually seeing are waves with different amplitudes. 3  They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different.avelength is a property of a wave that most people (once they know what to look for) can spot quickly and easily, and use it as a way of telling waves apart. Look at the following diagram... Figure 1. 1  Any of the parts of the wave that are pointing up like mountains are called crests.
