An ac voltage V = 0.5 sin (100 rt) volt is applied, in turn, across a half-wave rectifier and a full-wave rectifier. The frequency of the output voltage across them respectively will be

(A) 25 Hz, 50 Hz
(B) 25 Hz, 100 Hz
(C) 50 Hz, 50 Hz
(D) 50 Hz, 100 Hz

Ans. the correct answer is option (D) $50\text{Hz}$ for the half-wave rectifier and $100\text{Hz}$ for the full-wave rectifier.
