Part D A maser is a laser-type device that produces electromagnetic waves with frequencies in the By how many seconds would a hydrogen maser clock be off after a time interval equal to the age microwave and radio-wave bands of the of the earth? electromagnetic spectrum. You can use the radio Express your answer in seconds. 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 t= S remarkable accuracy to which it has been measured.) Submit Request
