spectrum

spec·trum   (spěk'trəm)    n.   pl. spec·tra (-trə) or spec·trums Physics The distribution of a characteristic of a physical system or phenomenon, especially: The distribution of energy emitted by a radiant source, as by an incandescent body, arranged in order of wavelengths. The distribution of atomic or subatomic particles in a system, as in a magnetically resolved molecular beam, arranged in order of masses. A range of values of a quantity or set of related quantities. A broad sequence or range of related qualities, ideas, or activities: the whole spectrum of 20th-century thought. A graphic or photographic representation of such a distribution. A range of values of a quantity or set of related quantities. A broad sequence or range of related qualities, ideas, or activities: the whole spectrum of 20th-century thought. [Latin, appearance, from specere, to look at; see spek- in Indo-European roots.]

spectrum

The range of wavelengths characteristic of a specific type of radiation.

Note: The spectrum making up visible light contains light in the colors violet, indigo, blue, green, yellow, orange, and red, with violet having the shortest wavelength and highest frequency, and red having the longest wavelength and lowest frequency.

n. pl. spec·trums or spec·tra (-trə)

1. The distribution of a characteristic of a physical system or phenomenon, especially the distribution of energy emitted by a radiant source arranged in order of wavelengths.

2. The color image presented when white light is resolved into its constituent colors: red, orange, yellow, green, blue, indigo, violet.

3. The plot of intensity as opposed to wavelength of light emitted or absorbed by a substance, usually characteristic of the substance and used in qualitative and quantitative analysis.

4. The distribution of atomic or subatomic particles in a system, as in a magnetically resolved molecular beam, arranged in order of masses.

5. The group of pathogenic organisms against which an antibiotic or other antibacterial agent is effective.
