-
aberration, distortion, optical aberration
an optical phenomenon resulting from the failure of a lens or mirror to produce a good image
-
absorption band
a dark band in the spectrum of white light that has been transmitted through a substance that exhibits absorption at selective wavelengths
-
diffraction
when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
-
fringe, interference fringe
one of the light or dark bands produced by the interference and diffraction of light
-
incidence
the striking of a light beam on a surface
-
optical illusion
an optical phenomenon that results in a false or deceptive visual impression
-
pleochroism
the phenomenon of different colors appearing when certain crystals are viewed from different directions
-
polarisation, polarization
the phenomenon in which waves of light or other radiation are restricted in direction of vibration
-
parallax
the apparent displacement of an object as seen from two different points that are not on a line with the object
-
Tyndall effect
the phenomenon in which light is scattered by very small particles in its path; it makes a beam of light visible; the scattered light is mainly blue
-
apparent motion, apparent movement, motion, movement
an optical illusion of motion produced by viewing a rapid succession of still pictures of a moving object
-
chromatic aberration
an optical aberration in which the image has colored fringes
-
dichroism
pleochroism of a crystal so that it exhibits two different colors when viewed from two different directions
-
mirage
an optical illusion in which atmospheric refraction by a layer of hot air distorts or inverts reflections of distant objects
-
spherical aberration
an optical aberration resulting in a distorted image
-
trichroism
pleochroism of a crystal so that it exhibits three different colors when viewed from three different directions
-
X-ray diffraction
the scattering of X rays by the atoms of a crystal; the diffraction pattern shows structure of the crystal
-
annual parallax, heliocentric parallax
the parallax of a celestial body using two points in the earth's orbit around the sun as the baseline
-
diurnal parallax, geocentric parallax
the parallax of a celestial body using two points on the surface of the earth as the earth rotates
