Question

question: which device picks up sound waves and converts them into a suitable electric current with the same pattern as the sound waves? answer options: select one of four microphone antenna oscillator modulator

Explanation:

• A microphone is a device that captures sound waves (mechanical energy) and converts them into an electrical current with a pattern matching the sound waves.
• An antenna is used for transmitting or receiving electromagnetic waves (like radio waves), not sound waves.
• An oscillator generates a periodic electrical signal, not convert sound waves.
• A modulator is used to modify a carrier wave (e.g., for signal transmission), not convert sound to electrical signals with the same pattern.

A. Microphone
