Final answer:
The frequency of the output voltage from a half-wave rectifier, when given a 60 Hz input, remains at 60 Hz as it only removes half of the AC waveform without altering the frequency.
Step-by-step explanation:
The subject of the question is a concept from Physics, specifically the behavior of a half-wave rectifier when subjected to an alternating current (AC) voltage. When a 60 Hz sinusoidal voltage is applied to a half-wave rectifier, it essentially allows only one half of the AC cycle to pass through, effectively eliminating the negative (or positive, depending on the orientation of the diode) part of the cycle. The half-wave rectifier does not change the frequency of the original signal; it only modifies the waveform. Thus, if the input frequency is 60 Hz, the output frequency will also be 60 Hz, as each cycle of the input waveform still corresponds to a single cycle of the output, albeit half of the original sine wave is missing.
