table, tabular array
a set of data arranged in rows and columns

matrix
(mathematics) a rectangular array of quantities or expressions set out by rows and columns; treated as a single element and manipulated according to rules

row
a linear array of numbers, letters, or symbols side by side

column
a vertical array of numbers or other information

panoply
a complete and impressive array

bank
an arrangement of similar objects in a row or in tiers

spectrum
an ordered array of the components of an emission or wave

correlation matrix
a matrix giving the correlations between all pairs of data sets

correlation table
a twoway tabulation of the relations between correlates; row headings are the scores on one variable and column headings are the scores on the second variables and a cell shows how many times the score on that row was associated with the score in that column

contents, table of contents
a list of divisions (chapters or articles) and the pages on which they start

actuarial table, statistical table
a table of statistical data

calendar
a tabular array of the days (usually for one year)

file allocation table
the part of a floppy disk or hard disk where information is stored about the location of each piece of information on the disk (and about the location of unusable areas of the disk)

periodic table
(chemistry) a tabular arrangement of the chemical elements according to atomic number as based on the periodic law

dot matrix
a rectangular matrix of dots from which written characters can be formed

square matrix
a matrix with the same number of rows and columns

real matrix
a matrix whose elements are all real numbers

transpose
a matrix formed by interchanging the rows and columns of a given matrix

absorption spectrum
the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths

action spectrum
the efficiency with which electromagnetic radiation produces a photochemical reaction plotted as a function of the wavelength of the radiation

atomic spectrum
(physics) a spectrum of radiation caused by electron transitions within an atom; the series of spectrum lines is characteristic of the element

electromagnetic spectrum
the entire frequency range of electromagnetic waves

emission spectrum
spectrum of electromagnetic radiation emitted by a selfluminous source

infrared spectrum
the spectrum of infrared radiation

line spectrum
a spectrum in which energy is concentrated at particular wavelengths; produced by excited atoms and ions as they fall back to a lower energy level

mass spectrum
a distribution of ions as shown by a mass spectrograph or a mass spectrometer

microwave spectrum
the part of the electromagnetic spectrum corresponding to microwaves

radio spectrum, radiofrequency spectrum
the entire spectrum of electromagnetic frequencies used for communications; includes frequencies used for radio and radar and television

acoustic spectrum, sound spectrum
the distribution of energy as a function of frequency for a particular sound source

ultraviolet spectrum
the spectrum of ultraviolet radiation

color spectrum, visible spectrum
the distribution of colors produced when light is dispersed by a prism
