Physics.findConstants

Returns an array of objects describing physical constants whose names match the search string.

Syntax

findConstants(searchString?)

Parameters

• searchString optional

  A constant name (full or partial) to search for.

  If omitted, returns all constants.

Return value

An array of objects describing physical constants.

Each physical constant object contains the following properties:

• name - the name of the constant

• value - the value of the constant

• unit - the string describing the unit of the constant

• uncertainty - the uncertainty of the constant

If no constants were found, returns an empty array.

Examples

Physics.findConstants("wien")

[{
  name: "Wien displacement law constant",
  value: 0.0028977685,
  unit: "m K",
  uncertainty: 5.1e-9
}, {
  name: "Wien frequency displacement law constant",
  value: 58789257570,
  unit: "Hz K^-1",
  uncertainty: 0
}, {
  name: "Wien wavelength displacement law constant",
  value: 0.002897771955,
  unit: "m K",
  uncertainty: 0
}]
