When a mechanical wave propagates through a physical medium, the particles of the medium oscillate about their mean positions with their positions being sinusoidal functions of time. The maximum displacement of each particle relative to its mean position is the amplitude of the w...
To identify each of the 64 values, there are eight levels of inphase (roughly speaking, a phase shift) and eight levels of quadrature (roughly speaking, the amplitude of a wave). Each time a symbol is transmitted, it may take on one of eight phase shifts and one of eight amplitude ...

wave. The amplitude of an ocean wave, for example, is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. See more atwave....

is the greatest distance reached to either side of the central rest position. Amplitude is important in the description of awavephenomenon such as light or sound. In general, the greater the amplitude of the wave, the more energy it transmits (e.g., a brighter light or a louder sound)....
First of all, the amplitude of a wave has nothing to do with its wavelength or its period. Basically here we only have the wavelength so it is... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a qu...

The use of a sound wave created by an external source and directed along the positive column of a nitrogen discharge in order to make the discharge pass to the contracted state is studied experimentally. A phenomenon involving a jump in the sound wave amplitude, caused by the discharge contract...
