lens

flat,smooth mirror that reflects light to form upright,virtual images

• plane mirror
• convex mirror
• concave mirror
• reflecting telescope
• focal point

an image formed by diverging light rays that is perceived by the brain,even though the light rays do not actually originate from the place where the image appears to be located

• real image
• virtual image
• fake image
• optical axis
• retina

a reflective surface that curves inward and can magnify objects or create real images

• plane mirror
• convex mirror
• concave mirror
• reflecting telescope
• focal length

imaginary straight line that is perpendicular to the surface at the center of a mirror or lens

• virtual image
• real image
• retina
• optical axis
• focal point

the point on the optical axis of a curved mirror or lens where light rays that are initially parallel to the optical axis converge after striking the mirror or lens

• real image
• virtual image
• retina
• optical axis
• focal point

distance from the center of a lens or mirror to the focal point

• focal length
• virtual image
• retina
• optical axis
• focal point

-an image that appears at a certain location as a result of rays of light converging at that location

• virtual image
• real image
• convex mirror
• sclera
• focal point

-a reflective surface that curves outward,away from the viewer,and forms a reduced,upright,virtual image

• plane mirror
• concave mirror
• convex mirror
• reflecting telescope
• lens

a lens that is thicker in the middle than at the edges and can form real or virtual images

• concave lens
• lens
• convex mirror
• convex lens
• refracting telescope

a lens that is thicker at the edges than in the middle,causes light rays to diverge and forms reduce,upright,virtual images;often used in combination with other lenses

• concave mirror
• microscope
