is an increase or decrease in size of an image produced by an optical system compared to the true size
Magnification
a transparent refracting device that is thicker in the middle than at the edges
concave lens
a transparent refracting device that is thinner in the middle than at the edges
concave lens
the separation of light into its spectrum
dispersion
concave on both sides
biconcave
convex on both sides
biconvex
light rays coming out of it come together at a point – they converge
converging lens
causes a beam of parallel rays to diverge after refraction, as from a virtual image
diverging lens
images that are formed in locations where light does not actually reach
virtual image
an image that is located in the plane of convergence for the light rays
real image
refracting and focusing light so that objects appear clearly
contact lenses
distance of an object that is placed from the point of an incidence on the mirror
object distance
distance from the point of incidence of the mirror to the image
image distance
a convex lens that is used to make a magnified image of an object
magnifying glass
bending of a wave when it enters a medium where its speed is different
Refraction
can calculate the image distance for either real or virtual images and for either positive on negative lenses
thin lens equation
point at where rays or waves meet after reflection or refraction
focal point
a technique for generating an image by tracing the path of light
ray tracing
angle of reflection equals the angle of incidence
flat mirror
the distance between the lens and the image sensor when the subject is in focus
focal length
