There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...

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 ...

It is also the time taken for one whole wave to pass a point. Period is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. It should be noted ...
