A maser is a laser-type device that produces
electromagnetic waves with frequencies in the
microwave and radio-wave bands of the
Part B
electromagnetic spectrum. You can use the radio
waves generated by a hydrogen maser as a
standard of frequency. The frequency of these
waves is 1,420,405,751.786 hertz. (A hertz is
another name for one cycle per second.) A clock
controlled by a hydrogen maser is off by only 1 s in
100,000 years. (The large number of significant
figures given for the frequency simply illustrates the
remarkable accuracy to which it has been
measured.)
