Learn More About Frequency
Scientific Overview
Frequency is the number of occurrences of a repeating event per unit of time. It is measured in hertz (Hz) and is the reciprocal of the period of oscillation or wave motion.
Historical Background
The concept of frequency was formally defined in the 19th century with the development of wave theory. Heinrich Hertz conducted pioneering experiments in electromagnetic waves, and the unit hertz is named after him.
Real-World Applications
Electronics
Frequency determines the operation of oscillators, filters, and communication systems.
Music
Musical pitch is determined by the frequency of sound vibrations.
Medicine
Medical imaging techniques like MRI and ultrasound rely on specific frequencies.
Telecommunications
Radio, television, and cellular networks operate at designated frequency bands.
Interesting Facts
- Human hearing range is typically 20 Hz to 20,000 Hz.
- The standard tuning note A4 has a frequency of 440 Hz.
- GPS satellites transmit at frequencies around 1.5 GHz.
- The Schumann resonance of Earth's atmosphere is about 7.83 Hz.
