light

 [līt]
electromagnetic radiation with a range of wavelength between 390 (violet) and 770 (red) nanometers, capable of stimulating the subjective sensation of sight; sometimes considered to include ultraviolet and infrared radiation as well.
idioretinal light (intrinsic light) the sensation of light in the complete absence of external stimuli.
polarized light light of which the vibrations are made over one plane or in circles or ellipses.
Wood's light ultraviolet radiation from a mercury vapor source, transmitted through a nickel-oxide filter (Wood's filter or glass), which holds back all but a few violet rays and passes ultraviolet rays of wavelength around 365 nm; used in diagnosis of fungal infections of the scalp and erythrasma, and to reveal the presence of porphyrins and fluorescent minerals.

po·lar·ized light

light in which, as a result of reflection or transmission through certain media, the vibrations are all in one plane, transverse to the ray, instead of in all planes.

polarized light

[po′lərīzd]
Etymology: L, polus + AS, leoht
light that is propagated in such a way that the radiation waves occur in only one direction in the vibration plane and not at random.

po·lar·ized light

(pō'lăr-īzd līt)
Light in which, as a result of reflection or transmission through certain media, the vibrations are all in one plane, transverse to the ray, instead of in all planes.

polarized light

light passed through a medium, so that its vibrations are confined to one plane

polarized light,

n electromagnetic radiation within the range of visible light that has a specific plane of polarization.

light

electromagnetic radiation with a range of wavelength between about 390 nm (violet) and 770 nm (red), capable of stimulating the subjective sensation of sight; sometimes considered to include ultraviolet and infrared radiation as well.

light beam diaphragm
adjustable lead shutters at the aperture of an x-ray tube. Usually includes a light bulb which delimits the area covered by the beam at the cassette level.
light cattle
store class cattle off range and destined for movement onto irrigated pasture or into feedlot for fattening.
light-dark cycles
an important environmental factor in proper housing of laboratory animals for optimal health and reproductive cycling. Most species do well on a 12:12 light-dark cycle but in rabbits more light for females and less for males is recommended.
polarized light
light of which the vibrations are made over one plane or in circles or ellipses.
light sensitization
light sheep
sheep light in condition off subsistence range and destined to go to irrigated pasture or into a feedlot for fattening.
light stimulus
Wood's light
see wood's light.
