cycles/second
Definition
Noun The unit of frequency in the International System of Units (SI), defined as one complete cycle of a periodic phenomenon occurring per second. It is synonymous with the hertz (Hz).
Usage
This term is used in scientific and technical contexts, particularly in physics and engineering, to measure the frequency of waves, oscillations, or repeating events. * The alternating current in many countries has a frequency of 50 cycles/second. * The processor's clock speed was measured in millions of cycles/second (megahertz).
Advanced Usage
- While "cycles/second" is a descriptive term, the official SI unit name hertz (Hz) is overwhelmingly preferred in modern technical writing and communication.
- The term can be used with standard SI prefixes (e.g., kilo-cycles/second, mega-cycles/second).
Variants and Related Words
- Hertz (Hz): The standard international unit of frequency, exactly equivalent to one cycle per second.
- Frequency: The rate at which a repeating event occurs, measured in cycles/second or hertz.
- Period: The duration of one cycle, which is the reciprocal of the frequency (Period = 1 / frequency).
Synonyms
- Hertz (Hz)
- cps (abbreviation for cycles per second)
Notes
- The term "cycles/second" is considered somewhat dated but remains understandable. In most formal and technical contexts, "hertz" is the correct and preferred term.
Noun
-
the unit of frequency; one hertz has a periodic interval of one second
