Common Scenarios
Frequency relates not only to sound, light, and radio but also to mechanical and electronic devices. In FM radio, frequency (MHz) determines the station. When buying a computer, the processor's clock speed (GHz) marks its computing power.
History & Background
In the 19th century, Heinrich Hertz experimentally confirmed the existence of electromagnetic waves, laying the foundation for modern communications. In the 20th century, humanity could measure and control extremely high frequencies.
Conversion Details
Frequency conversion is based on hertz (Hz), the number of occurrences per second.
Common conversions: 1 kHz = 1,000 Hz, 1 MHz = 1,000 kHz, 1 rpm ≈ 0.0167 Hz.
