monochromatic
Art History
(adjective)
Black and white, or using one color.
Physics
(adjective)
Describes a beam of light with a single wavelength (i.e., of one specific color or frequency).
Examples of monochromatic in the following topics:
-
Lasers
- A laser is a device that emits monochromatic light through a process of optical amplification based on the stimulated emission of photons.
- A laser is a device that emits monochromatic light (electromagnetic radiation).
- A material with many atoms in an excited state may thus result in radiation that is very monochromatic, but the individual photons would have no common phase relationship and would emanate in random directions.
-
The Michelson Interferometer
- Colored and monochromatic fringes in a Michelson interferometer: (a) White light fringes where the two beams differ in the number of phase inversions; (b) White light fringes where the two beams have experienced the same number of phase inversions; and (c) Fringe pattern using monochromatic light (sodium D lines).
-
Stokes Parameters
- The four Stokes parameters satisfy the following relationship for a truly monochromatic wave
-
Photochemistry
- Thus, we may define quantum yield as "the number of moles of a stated reactant disappearing, or the number of moles of a stated product produced, per einstein of monochromatic light absorbed
-
Illuminated Manuscripts
- Pucelle's work was characterized by delicate figures and the use of the primarily monochromatic grisaille technique with additional touches of color.
-
Young's Double Slit Experiment
- The example in uses two coherent light sources of a single monochromatic wavelength for simplicity.
- It should be noted that this example uses a single, monochromatic wavelength, which is not common in real life; a more practical example is shown in .
-
The Rayleigh Criterion
- (a) Monochromatic light passed through a small circular aperture produces this diffraction pattern.
-
Newton's Rings
- When viewed with monochromatic light, Newton's rings appear as alternating bright and dark rings; when viewed with white light, a concentric ring pattern of rainbow colors is observed.
-
Aberrations
- This can eventually cause a monochromatic image to distort vertically or horizontally.
-
Color Schemes
- An analogous color scheme creates a rich, monochromatic look in an artwork.
