camera

A(n) ________ works by gathering and bending light with a lens.

New cards
2

Astigmatism

________ causes blurry vision at all distances.

New cards
3

Cornea

________: causes light rays to bend so that they converge.

New cards
4

concave mirror

When an object is farther from a(n) ________ than twice the focal length, the image that is formed is real, smaller, and upside down, or inverted.

New cards
5

Corrective lenses

________ also have an uneven curvature, canceling out the effect of an uneven cornea.

New cards
6

Concave Lenses

________: thinner in the middle and thicker at the edges.

New cards
7

focal point

A light placed at the ________ is reflected in a beam.

New cards
8

convex mirror

A(n) ________ is said to have a wide field of view.

New cards
9

Optical Axis

________: an imaginary straight line drawn perpendicular to the surface of the mirror at its center.

New cards
10

telephoto

A(n) ________ lens creates a larger image of an object than a wide- angle lens does.

New cards
11

Hubble telescope

The ________ is a type of reflecting telescope that uses two mirrors to collect and focus light to form an image.

New cards
12

Virtual Image

________: An image which your brain perceives even though no light rays pass through it.

New cards
13

real image

Reflecting telescopes use two mirrors to create a(n) ________, which then is magnified by a convex lens.

New cards
14

Microscope

________: uses two convex lenses with relatively short focal lengths to magnify small, close objects.

New cards
15

Concave lenses

________ are used in some types of eyeglasses and some telescopes.

New cards
16

concave mirror

A flashlight uses a(n) ________ to create a beam of light.

New cards
17

convex mirror

The reflected rays diverge and never meet, so the image formed by a(n) ________ is a virtual image.

New cards
18

optical axis

When light rays travel toward the mirror parallel to the ________, they reflect through the focal point.

New cards
19

virtual image

The ________ formed by a plane mirror is always upright and appears to be as far behind the mirror as the object is in front of it.

New cards
20

microscope

A(n) ________ uses two convex lenses to magnify small objects.

New cards
21

light rays

When ________ approach a convex lens traveling parallel to its optical axis, the rays are refracted toward the center of the lens.

New cards
22

Convex Mirror

________: A mirror that curves outward like the back of a spoon.

New cards
23

concave mirror

A(n) ________ has an optical axis and a focal point.

New cards
24

telescope

A(n) ________ uses a lens or a concave mirror that is much larger than your eye to gather more of the light from distant objects.

New cards
25

convex mirror

Light rays that hit a(n) ________ diverge, or spread apart, after they are reflected.

New cards
26

concave mirror

The image that is formed by a(n) ________ changes depending on where the object is located relative to the focal point of the mirror.

New cards
27

Plane Mirror

a flat, smooth mirror

New cards
28

Virtual Image

An image which your brain perceives even though no light rays pass through it

New cards
29

Concave Mirror

the surface of a mirror is curved inward

New cards
30

Optical Axis

an imaginary straight line drawn perpendicular to the surface of the mirror at its center

New cards
31

Focal Point

a point on the optical axis

New cards
32

Focal Length

The distance from the center of the mirror to the focal point

New cards
33

Real Image

formed when light rays converge to form the image

New cards
34

Convex Mirror

A mirror that curves outward like the back of a spoon

New cards
35

Convex Lenses

thicker in the middle than at the edges

New cards
36

Concave Lenses

thinner in the middle and thicker at the edges

New cards
37

Cornea

causes light rays to bend so that they converge

New cards
38

Retina

the inner lining of your eye

New cards
39

Refracting Telescope

uses two convex lenses to gather and focus light from distant objects

New cards
40

Reflecting Telescope

uses a concave mirror, a plane mirror, and a convex lens to collect and focus light from distant objects

New cards
41

Microscope

uses two convex lenses with relatively short focal lengths to magnify small, close objects
