A maser is a laser-type device thatproduces electromagnetic waves with frequencies in the microwaveand radio-wave bands of the electromagnetic spectrum. You can use theradio 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 anothername for one cycle per second.) A clock controlled by a hydrogenmaser is off by only 1 s in 100,000 years. For the following questions,use only three significant figures. (The large number of significant figuresgiven for the frequency simply illustrates the remarkable accuracyto which it has been measured.) By how many seconds would a hydrogen maser clock be off after a time interval equal to the age of the earth?
