Perceivable by the eye; capable of being seen; perceptible; in view; as, a visible star; the least spot is visible on white paper.
The region of the electromagnetic spectrum which is visible by the human eye. Light in the visible region falls between 400-700 nm.
Visible wavelengths range from 0.4 to 0.7 µm. If only one sensor receives from these wavelengths you will see grayscales, not colour. Colour requires scanners with sensors at each of the wavelengths for the colours to be combined. See also IR and WV.
The small range of the electromagnetic spectrum that human eyes perceive as light. The visible spectrum ranges from about 400 to 700 nm, corresponding to blue through red light.
Electromagnetic radiation at wavelengths which the human eye can see. We perceive this radiation as colors ranging from red (longer wavelengths; ~700 nanometers) to violet (shorter wavelengths; ~400 nanometers.) Also called " optical light".
perceptible especially by the eye; or open to easy view; "a visible object"; "visible stars"; "mountains visible in the distance"; "a visible change of expression"; "visible files"
obvious to the eye; "a visible change of expression"
being often in the public eye; "a visible public figure"
The region of the electromagnetic spectrum that can be seen by the human eye. Generally considered to be the 400-nm to 700-nm portion of the spectrum.
radiation Energy at wavelengths from 400 700 nm that is detectable by the eye.
Capable of being seen by the human eye. A sign may be visible without being readable or legible.
That part of the electromagnetic spectrum to which the human eye is sensitive, between about 0.4 and 0.7 micrometers. See spectrum.
Pertaining to radiant energy in the electromagnetic spectral range visible to the normal human eye (approximately 380 to 780 nm.
The region of the electromagnetic spectrum which is detectable to the human eye (approximately 0.4 to 0.7 microns).
Visible means capable of being seen, whether or not legible, without visual aid by a person of normal visual acuity.
