magnifying glass: the simplest of all optical instruments
retina: surface opposite the lens of the eye on which images form
astigmatism: condition in which eye is not exactly spherical
camera: a lightproof box with a lens at on end and a light-sensitive film at the other end.
aperture: opening behind the shutter of a camera.
compound microscope: optical device composed of two converging lenses.
refracting telescope: device used for observing heavenly bodies; consisting of two converging lenses
erecting lens: lens used to invert the image formed by the objective lens of a telescope
galilean telescope: first telescope developed.
binoculars: when two Galilean telescopes are mounted.
color: a property of the light seen by the human eye
electromagnetic spectrum: radiations with wavelengths that fall outside the visible spectrum.
incandescent light: light made up of most of the colors of the visible spectrum
fluorescent light: light produced by some minerals
spectroscopy: the analysis of spectra
magenta: a mixture of red and blue light
colorblind: when the nerves in someone's eyes are not sensitive enough to respond to certain colors.
diffraction: bending of light into a region behind an obstruction
plane polarized: when light vibrates in one direction it is said to be
phosphorescence: glow emitted by a substance after exposure to radiation
transparent material: material that can transmit nearly all the light in the ray because it offers little resistance to the passage of a light ray.
illuminance: the rate at which light energy is received by a unit of area of the surface
photometer: device that measures the intensity of a light source
light meter: instrument that measures the illuminance on a surface
