Parent topics
- International System of Units [r]: Metric unit system based on the metre, kilogram, second, ampere, kelvin, mole and candela. [e]
Subtopics
- 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]
- Metre (unit) [r]: Unit of length; one of the seven SI base units. [e]
- Second (physics) [r]: Unit of time; one of the seven SI base units. [e]}
- Electric constant [r]: A physical constant in the International System of Units (SI) relating capacitance to area in classical vacuum with an exact value ε0 = 107/(4πc02) F/m, c0 being the defined value for the speed of light in classical vacuum in the SI units. [e]
- Magnetic constant [r]: A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2. [e]
- Vacuum (partial) [r]: A realizable vacuum with a gaseous pressure that is much less than atmospheric. [e]
- Vacuum (quantum electrodynamic) [r]: The term quantum electrodynamic vacuum, or QED vacuum, refers to the ground state of the electromagnetic field, which is subject to fluctuations about a dormant zero average-field condition. [e]
