Understanding Frequency Units
Frequency measures the number of occurrences of a repeating event per unit of time. The SI unit of frequency is the Hertz (Hz), equal to one cycle per second.
Common Frequency Units:
- Hertz (Hz): SI unit — 1 cycle per second
- Kilohertz (kHz): 1,000 Hz — AM radio, audio frequencies
- Megahertz (MHz): 1,000,000 Hz — FM radio, CPU clocks (older)
- Gigahertz (GHz): 1,000,000,000 Hz — modern CPUs, Wi-Fi, 5G
- Terahertz (THz): 10¹² Hz — infrared light, spectroscopy
- RPM: Revolutions per minute — motors, engines, hard drives
Real-world Examples:
- Human hearing range: 20 Hz – 20 kHz
- AC power (US): 60 Hz
- FM radio: 87.5 – 108 MHz
- Wi-Fi 2.4 GHz band: 2,400 – 2,500 MHz
- Wi-Fi 5 GHz band: 5,150 – 5,850 MHz
- Modern CPU: 3 – 5 GHz
