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....
(ii) Calculate the amplitude of the resultant sound wave at location X due to the interference of the wave that comes directly from the point source, and the wave that is reflected by the wall. Explain your reasoning.[2] 相关知识点: ...

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. ...
aAssuming that the amplitude of the electrical filed of the CW light wave from the TLS is E0 , and the polarization direction of the incident light from the TLS is aligned at an angle of relative to one principal axis of the PBS, the electrical field at the output of the PBS for ...

Make a signal which is 3 seconds long. The frequency is 50 Hz. The amplitude is 230 V rms (i.e. peak amplitude=325 V). The peak amplitude dips to 275 V for 1 second in the middle of the 3 second long signal.I
outcome, which is supported by a necessary but not sufficient condition - imposed on the largest singular value of the effective stability matrixWγ = (1 − γ) + γW. Then, in RC output training, whose design commonly amounts to two aspects. One is to determine the ...
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 ...
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...
