-
beam, beam of light, irradiation, light beam, ray, ray of light, shaft, shaft of light
a column of light (as from a beacon)
-
candle flame, candlelight
the light provided by a burning candle
-
corona
one or more circles of light seen around a luminous object
-
counterglow, gegenschein
a faint spot of light in the night sky that appears directly opposite the position of the sun; a reflection of sunlight by micrometeoric material in space
-
daylight
light during the daytime
-
firelight
the light of a fire (especially in a fireplace)
-
fluorescence
light emitted during absorption of radiation of some other (invisible) wavelength
-
friar's lantern, ignis fatuus, jack-o'-lantern, will-o'-the-wisp
a pale light sometimes seen at night over marshy ground
-
gaslight
light yielded by the combustion of illuminating gas
-
glow, glowing, radiance
the amount of electromagnetic radiation leaving or arriving at a point on a surface
-
glow
a steady even light without flames
-
half-light
a greyish light (as at dawn or dusk or in dim interiors)
-
glow, incandescence
the phenomenon of light emission by a body as its temperature is raised
-
lamplight
light from a lamp
-
luminescence
light not due to incandescence; occurs at low temperatures
-
meteor, shooting star
a streak of light in the sky at night that results when a meteoroid hits the earth's atmosphere and air friction causes the meteoroid to melt or vaporize or explode
-
Moon, moonlight, moonshine
the light of the Moon
-
starlight
the light of the stars
-
sun, sunlight, sunshine
the rays of the sun
-
scintillation
(physics) a flash of light that is produced in a phosphor when it absorbs a photon or ionizing particle
-
streamer
light that streams
-
torchlight
light from a torch or torches
-
twilight
the diffused light from the sky when the sun is below the horizon but its rays are refracted by the atmosphere of the earth
-
aureole, corona
the outermost region of the sun's atmosphere; visible as a white halo during a solar eclipse
-
autofluorescence
self-induced fluorescence
-
sky glow
illumination of the night sky in urban areas
-
heat ray
a ray that produces a thermal effect
-
high beam
the beam of a car's headlights that provides distant illumination
-
bioluminescence
luminescence produced by physiological processes (as in the firefly)
-
chemiluminescence
luminescence resulting from a chemical reaction as the oxidation of luciferin in fireflies
-
bolide, fireball
an especially luminous meteor (sometimes exploding)
-
moon ray, moon-ray, moonbeam
a ray of moonlight
-
sunburst
a sudden emergence of the sun from behind clouds
-
sunbeam, sunray
a ray of sunlight
-
laser beam
a beam of light generated by a laser
-
low beam
the beam of a car's headlights that provides illumination for a short distance
-
phosphorescence
a fluorescence that persists after the bombarding radiation has ceased
