Most scales are based on the amplitude of seismic waves recorded on seismometers ... Then there are also measures of earthquake shaking intensity. The intensity from one earthquake varies greatly from ...

As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. Don't get confused with this quantity frequency. It is not a ...

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...

Velocity (and therefore pressure) is greatest mid-way between the maximum displacement of the vibrating body, and we can graph the resulting relationship between amplitude and sound pressure in the ...

Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an analog telephone conversation, the voice waves on both sides are modulating the voltage of the ...

This grating can therefore be used either to steer a beam, modulate its intensity or sensitively ... polarization and amplitude of the applied sound wave. This approach offers far more rapid ...
