In half - wave rectification, what is the output frequency, if the
input frequency is 50 Hz ? What is the output frequency of a full - wave rectifier
for the same input frequency ?

Explanation

Input frequency = 50 Hz
For a half-wave rectifier, the output frequency is equal to the input frequency.
`therefore"Output frequency" = 50 Hz`
For a full-wave rectifier, the output frequency is twice the input frequency.
`therefore"Output frequency" = 2 xx 50 = 100 Hz`
