Science Ch 14 Vocab Flashcards
Flat, smooth mirror that reflects light to form upright, virtual images
Plane mirror
Am image formed by diverging light rays that is perceived by the brain, even though no actual light rays pass through the place where the image seems to be located
Virtual image
A reflective surface that curves inward and can magnify objects or create beams of light
Concave mirror
Imaginary straight line that is perpendicular to the center of a concave mirror
Optical axis
The point on the optical axis of a concave mirror or convex lens where light rays pass through after they strike the mirror or lens
Focal point
Distance from the center of a lens or mirror to the focal point
Focal length
An image formed by light rays that converge to pass through the place where the image is located
Real image
A reflective surface that curves outward and forms a reduced, upright, virtual image
Convex mirror
A lens that is thicker in the middle than on the edges and can form real or virtual images
Convex lens
A lens that is thicker at the edges than in the middle
Concave lens
Transparent covering on the eyeball through which light enters the eye
Cornea
Inner lining of the eye that has cells which convert light images into electrical signals for interpretation by the brain
Retina
Use two complex lenses to gather and focus light from distant objects
Refracting telescope
Uses a concave mirror, plane mirror and convex lens to collect and focus light from distant objects
Reflecting telescope
Uses convex lenses to magnify small, close objects
Microscope
