Corpuscular the theory which explains light as a stream of invisible bundles of energy
Photons the visible bundles of energy
, Electromagnetic Theory The theory which explains light as moving in a series of wave pulsations.
186,000 miles per second the speed of light in air
ray a point of light pulsating in a straight line
all colors the colors that visible or white light are composed of
base a prism will bend light towards its
one meter one diopter prism will deviate a ray of light one centimeter in a distance of
apex the image being viewed through prism will always be displaced towards its
refraction the bending of light as it passed from a medium of lesser density to a medium of
greater density is known as
refractive index the speed of light in air divided by the speed of light in a material
optical center the single point on an optical lens through which light may pass without being
deviated
converging/against motion plus lenses can be characterized by these two attributes
diverging/with motion minus lenses can be characterized by these two attributes
minus spheres simple myopia or nearsightedness can be corrected with these type of lenses
plus spheres simple hyperopia or farsightedness can be corrected with these type of lenses
cylinder lenses an eye which requires a different correction in different meridians can be
corrected with these type of lenses
530 mm the radius of curvature of a one diopter lens
+1.75 The total power of a lens with a +6.00 diopter front surface and a -4.25 diopter
back surface lens.
two plus surfaces a biconvex lens
1 meter the focal length of a one diopter lens
+3.00 +2.00 x 005 the correction transposition of the following rx:
+5.00 -2.00 x 095
out the pupillary distance ground too wide for a plus Rx will result with this type of
prism base
