100
lens: thinner at center
What is a concave lens?
100
separates white light into colors of the visible spectrum
What is a prism?
100
a muscle that controls how much light enters the eye; also comes in many colors
What is the iris?
100
lens: used to correct vision problems
What is a concave and convex lens?
100
a tough, clear covering; helps protect the eye; this begins bending light to make an image
What is the cornea?
200
lens: thicker at center
What is a convex lens?
200
the name we use to remember the colors of the visible spectrum
What is ROY G. BIV?
200
the dark circle in the center of the eye; it's a hole that lets light into the inner eye
What is the pupil?
200
the bending of light rays as they pass from one material to another
What is refraction?
200
the bundle of nerve fibers that carry information from one part of the eye to the brain
What is the optic nerve?
300
lens: bends light rays toward one another
What is a convex lens?
300
the colors of the visible spectrum will always be in the same order
What is true?
300
the thick, tough, white outer covering of the eyeball
What is the sclera?
300
bouncing of light from a surface
What is reflection?
300
the part of the eye where light is refracted
What is the lens?
400
lens: bends light rays away from one another
What is a concave lens?
400
cameras, eyeglasses, mirrors, telescopes - does not refract light
What is mirrors?
400
detects images focused by other parts of the eye
What is the retina?
400
the direction that light rays are refracted after they pass through a convex lens
What is toward one another?
400
has light-sensitive cells at the back of the eye that detects focused images
What is the retina?
500
lens: refracts light in a predictable way
What is a concave and convex lens?
500
how a prism forms a visible spectrum
What is bending white light?
500
a clear, flexible structure that makes an image on another part of the eye
What is the lens?
500
causes the pencil to appear broken, even though it is not
What is refraction?
