GeneralClass 12AllAnswered 27 Mar 2026
Answer
The two main frequency classifications are:
- Natural (fundamental) frequency: The inherent frequency at which a system oscillates when disturbed (like a guitar string's primary vibration)
- Forced frequency: The frequency imposed on a system by an external force
Alternatively, frequencies can be categorized as:
- Audio frequencies (20 Hz - 20 kHz): Sound we can hear
- Radio frequencies (3 kHz - 300 GHz): Used for wireless communication
