_ is used for the rectification of the electromagnetic waves.
Correct answer: C. Crystal diode
- A. Audible
- B. Compare
- C. Crystal diode
- D. Valence band
Explanation
Diodes are used for the rectification of electromagnetic waves. They convert alternating current (AC) into direct current (DC) by allowing current to flow in one direction only.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
