Terms
undefined, object
copy deck
- wall
-
type of object
opaque - refraction
- the bending of light due to a change in speed
- optical fibers
-
*are strnads of very pure glass
*tranmit information as flashes of light
*do not help security devices or scalpels - cones are sensitive to
- a particular color
- laser light is produced
- normal atom becomes excited and produces 2 identical atoms
- tree
-
type of object
opaque - black light
- absorbs all color hitting it
- pupil
-
light enters here (47)
- cornea
- does mos of the refraction of light (48)
- lens
- *is a soft flexible lens (46)
- plane mirrors
-
*produce vital images
*images appear on the otherside of the mirror
*used in homes and industries - polarized light
- waves are vibrating in the same direction
- focal point
- is where reflected or refracted light rays meet
- a luminous object
- sends out light rays n all directions in straight lines.
- bread
-
what happens to the light
absorbs - rods are sensitive to
- light and dark
- refraction of light by the earths atmosphere
- is a mirage
- retina
- is where the image if focused (49)
- lasers
-
*produce an intense beam of light of one color
*helps audio and video cds - convex lens
-
*image is larger when close up.
*image is upside down and smaller when far away.
*corrective lens for a farsightedness person
*it converges the rays - Light travels
- in sraight paths.
- mirror

what happens to the light
reflect - plastic bag

what happens to the light
transmit - magnifying glass
-
what happens to the light
transmit
refract - Iris
- controls the amount of light in the eye (45)
- images are upside down when
- formed in the back of the eyes
- reflection of light
- is the bouncing back of light off a surface of an object.
- optic nerve
- (50)
- matches
-
what happens to the light
luminous - tent
-
type of object
translucent - does not contridict
- the wavelike or particlelike characteristics of light
- holograms
- are 3d images
- visible light spectrum
- all colors made up of white light
- white light
-
*reflects all light
*reflects all color hitting it
*abosrbs no color - convex mirrors
-
*used on cars (side and rearview mirrors)
*provides a large area of reflection
*thicker in the center than at the edges - concave lens
-
*image is smaller when close up
*image smaller when far away
*corrective lens for a nearsightedness person
*it diverges the rays - clear wrap
-
type of object
transparent - colors in longest to shortest
- red, orange, yellow, green , blue, indigo, violet
- glass
- type of object transparent
- when light strikes matter it is either
- transmitted, reflected or absorbed
-
concave mirrors
-
*used in make up mirrors
*image looks larger
*thinner in the center than at the edges
