Parent topics
- Time [r]: A fundamental quantity in physics - that what differs always between two inspections of the same system by the same observer. [e]
- International System of Units [r]: Metric unit system based on the metre, kilogram, second, ampere, kelvin, mole and candela. [e]
- Speed of light [r]: A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0 ≡ 299 792 458 m/s (exact). [e]
Subtopics
- Millisecond [r]: Add brief definition or description
- Microsecond [r]: Add brief definition or description
- Nanosecond [r]: Add brief definition or description
- Femtosecond [r]: Add brief definition or description
- Picosecond [r]: Add brief definition or description
- Year [r]: A unit of time measurement that corresponds to one revolution of the earth around the sun, approximately 365¼ days. [e]
- Month [r]: Unit of time originally corresponding approximately to one cycle of the moon's phases, or about 30 days or 4 weeks. [e]
- Week [r]: Time unit equal to a number of days, now usually seven calendar days, previously weeks of between 4 and 20 days have been used historically in various places. [e]
- Day [r]: Defined as 86,400 seconds, using the SI definition of second. [e]
- Hour [r]: Add brief definition or description
- Minute [r]: Add brief definition or description
- Metric units [r]: Obsolete term for a system of units in which the unit of length is the meter, the unit of mass the kilogram, and the unit of time the second. [e]
- Hertz [r]: The international (SI) unit of frequency, with units of inverse seconds, commonly called cycles per seocond. [e]
- Frequency [r]: For a periodic (i.e., repeating) phenomena, the number of repetitions per unit of time, usually one second; measured in Hertz [e]
- Electromagnetic wave [r]: A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons. [e]
- Light second [r]: Distance that light travels in vacuum in one second; 2.99792458 * 108m. [e]
- Hyperfine level [r]: Add brief definition or description
- Caesium [r]: A chemical element, having the chemical symbol Cs, and atomic number (the number of protons) 55. [e]
- Isotope [r]: Add brief definition or description
- Time [r]: A fundamental quantity in physics - that what differs always between two inspections of the same system by the same observer. [e]
- Film [r]: Add brief definition or description
- Cobalt [r]: Add brief definition or description
