Final answer:
The time for one cycle of the radio wave can be calculated by taking the reciprocal of its frequency. The frequency of the radio wave generated by a hydrogen maser is 1,420,405,751.786 Hertz.
Step-by-step explanation:
The time for one cycle of the radio wave can be calculated by taking the reciprocal of its frequency. The frequency of the radio wave generated by a hydrogen maser is 1,420,405,751.786 Hertz. Therefore, the time for one cycle can be calculated as:
1 cycle = 1 / frequency
1 cycle = 1 / 1,420,405,751.786 Hz
1 cycle = 7.0463 × 10-10 seconds
