1kHz = 1,000Hz\) \(1MHz = 1,000,000Hz\) The speed (or sometimes you might see it called velocity) of a wave (\(v\)) is how far the wave travels in a certain time. Wave speed is measured in metres ...

Most scales are based on the amplitude of seismic waves recorded on seismometers ... think of it in terms of the energy released by explosives: a magnitude 1 seismic wave releases as much energy as ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

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 ...

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. The amplitude (\(a\)) of a wave is the distance from the ...
