A maser is a laser-type device that produces electromagnetic waves
with frequencies in the microwave and radio-wave bands of the electromagnetic spectrum. You can use the radio waves generated by a hydrogen maser as a standard of frequency. The frequency of these waves is
What is the time for one cycle of the radio wave?
How many cycles occur in
How many cycles would have occurred during the age of the earth, which is estimated to be
By how many seconds would a hydrogen maser clock be off after a time interval equal to the age of the earth?
