amplitude i. The amplitude of a wave is the maximum displacement, or the maximum value, it attains from its mean position during a cycle. It is both positive and negative. With sound waves, the greater the amplitude, the louder is the sound. ...

5. The following figure shows the variations of a sound wave over time. E 、!time/s子Fig 5.1a)Comment on the volume of the sound and explain your answer.The volume is getting softer over time.The amplitude of the wave is decreasing over time.[2]b) The frequency of the sound is 60...
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 ...
A numerical method for determining the amplitude of a wave edge in shallow water approximation An algorithm to solve numerically the problem of determining the leading edge amplitude of a wave is constructed. The wave is generated by the initial cond... S Kabanikhin,OI Krivorot'K - 《Applied...
A wave is a disturbance of a physical quantity traveling in space. The simplest form of a wave is a sine wave propagating along one dimension x in a time t, characterized by A(x,t)=A0sin(kx−ωt), where A can stand for displacement (wave on a string or on water), ...

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....
