We can convert sound waves into electrical oscillations by _.
Correct answer: A. Microphone
- A. Microphone
- B. Television
- C. Radio
- D. None of these
Explanation
We can convert sound waves into electrical oscillations by using a device called a microphone. Microphones contain a diaphragm that vibrates in response to sound waves, which then converts these vibrations into electrical signals that represent the original sound.

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.
