A. sound waves into electrical energy
B. sound waves into light rays
C. electrical energy into sound waves
D. sound waves into magnetic currents
✅ The correct answer is option A.
Microphone is used to convert sound waves into electrical energy. Microphones are a type of transducer – a device which converts energy from one form to another. Microphones convert acoustical energy (sound waves) into electrical energy (the audio signal). Different types of microphone have different ways of converting energy but they all share one thing in common: The diaphragm.
