2Nd Grading Science Mirrors

Front 1

are formed when light strikes a reflecting surface such as a mirror or a lens

Back 1

images

Front 2

source of incident rays

Back 2

object

Front 3

picture formed by the reflected rays

Back 3

image

Front 4

occur when light rays actually intersect at the image, making them appear inverted or upside down

Back 4

real images

Front 5

occur when light rays do not actually meet at the image, but because the eye projects light rays backward, we are tricked into seeing an image that is erect or right side up (upright)

Back 5

virtual images

Front 6

(2) basic types of mirrors

Back 6

plane mirrors and spherical mirrors

Front 7

are the common, everyday flat mirrors that we see everywhere

Back 7

plane mirrors

Front 8

states that the image is always the same distance behind the mirror as the object is in front of the mirror

Back 8

law of plane mirrors

Front 9

second class of mirror in the form of a slice of a spherical surface

Back 9

spherical mirror

Front 10

(2) spherical mirrors

Back 10

concave mirror and convex mirror

Front 11

mirror that is curved inward like the hollow inside of a sphere. (coverging)

Back 11

concave mirror

Front 12

a mirror that is curved outward, like the outside if a sphere. (diverging)

Back 12

convex mirror

Front 13

will always produce a virtual image

Back 13

convex mirror

Front 14

the center if the circle of which the mirror represents a small arc

Back 14

center if curvature

Front 15

the point where parallel light rays converge

Back 15

focus

Front 16

the point where the mirror crosses the principal axis

Back 16

vertex

Front 17

a line drawn through the vertex, focus, and center if curvature of the mirror upon which the object rests

Back 17

principal axis

Front 18

the distance from the focus to the vertex of the mirror

Back 18

focal length

Front 19

the distance from the center of the curvature to rhe vertex of the mirror

Back 19

radius of curvature

Front 20

traces the path that light takes in order for an individual to view a point on the image of an object

Back 20

ray diagram

Front 21

technique to be able to describe the location, size, orientation and type of image formed by concave of a concave mirror

Back 21

ray diagramming

Front 22

ray that leaves a point on an object facing the mirror parallel to the principal axis

Back 22

principal ray

Front 23

ray that leaves the same point on the object and immediately passes through the focal point, hitting the mirror and reflecting parallel to the principal axis

Back 23

focal ray

Front 24

ray that leaves the same point on the object and passes through the center of curvature C of the mirror

Back 24

chief ray

Front 25

object beyond center of curvature

Back 25

smaller

Front 26

object at center of curvature

Back 26

same size

Front 27

object between center of curvature and focal point

Back 27

larger

Front 28

object at focal point

Back 28

no image

Front 29

object between the mirror and focal point

Back 29

virtual, upright, larger

Front 30

object at affinity

Back 30

smaller

Front 31

a shaped transparent material that refracts light to create an image

Back 31

lens

Front 32

(2) types of lens

Back 32

converging lens (convex lens) and diverging lens (concave lens)

Front 33

lens that is thicker at the middle

Back 33

converging or convex lens

Front 34

lens that is thinner at the middle than the edges

Back 34

diverging or concave lens

Front 35

of the lens is the line joining the centers of curvatures of its surface

Back 35

principal axis

Front 36

lens: the point where they converge

Back 36

principal focus

Front 37

lens: distance from the center of the lens

Back 37

focal length

Front 38

center of lens

Back 38

optical center

Front 39

lens: a ray that leaves the object parallel to the principal axis and is refracted by the lens to pass through the far focal point of a converging lens or the near focal point of a diverging lens

Back 39

principal ray

Front 40

lens: a ray that leaves the object and passes through the near focal point of a converging lens

Back 40
