A ray reflected from a retro-reflector
has an angle of reflection equal to the angle of incidence.
passes through the focal point.
forms a right angle with an incident ray
travels in the direction opposite that of the incident ray.
The back surfaces of automobile headlights are curved
because inverted, real images of filaments shine brighter.
to concentrate light in one direction.
for structural reasons not related to optics.
to get multiple images of the filament.
If you’re “farsighted,” the lenses in your eyes would produce an image further back than your retinas, so you need __________ lenses to correct this issue.
Converging lens
Diverging Lens
Biconvex lens
Biconcave lens
A human eye employs _________lens to form_________ images.
Converging……real
converging .... virtual
diverging .... real
diverging .... virtual
A magnifying glass uses a __________ lens because these lenses cause light rays to ________, or come together.

Biconcave
Convex
Biconvex

A camera employs a _____ lens to form _____ images.
converging .... real

In most cameras the location of the image is adjusted to appear on the film by changing the
position of the lens.
diameter of the diaphragm.
shape of the lens
focal length of the lens.
The first optical instruments which were used to magnify distant images.
Binoculars
Microscope
Telescope
Periscope
If you’re “nearsighted,” this means your eye lenses create images in front of the light-sensitive retina in your eye, and so you need diverging (concave) lenses to move the image further back.
Converging lens
Diverging Lens
Biconvex lens
Biconcave lens
