Home > Characteristic light

A light characteristic is a coded description displayed on a nautical chart under the chart symbol for a lighthouse, lightvessel or sea mark with a light on it, to indicate how that light is recognised visually and audibally.

An example of a light characteristic is Gp Oc(3).10s 15m 10M. This indicates the light is a Occulting Group of 3, every 10 seconds, 15 metres tall and visible for 10 nautical miles.

The following chart describes some of the different types of light characteristics:

Characteristic subgroupIn abstract algebra, a characteristic subgroup of a group G is a subgroup H of G invariant under each automorphism of G''. This means that if f : G → G is a group automorphism(a bijective homomorphism from the group G to itself), then for every x in	CharacteristicThe word characteristic has several meanings: In mathematics, see characteristic (algebra) characteristic function characteristic subgroup Euler characteristic method of characteristics In genetics, see characteristic (genetics).

Characteristic functionSome mathematicians use the phrase characteristic function synonymously with " indicator function". The indicator function of a subset A of a set B is the function with domain B whose value is 1 at each point in A and 0 at each point that is in B but not	Characteristic polynomialIn linear algebra, one associates a polynomial to every square matrix, its characteristic polynomial . This polynomial encodes several important properties of the matrix, most notably its eigenvalues, its determinant and its trace.
