MIRRORS

Question 1

Oldest optical instrument

Answer 1

Eye

Question 2

Light converges at a point when it strikes and reflects from the reflecting surface of the concave mirror. ALSO KNOWN AS CONVERGING MIRROR

Answer 2

CONCAVE MIRROR

Question 3

The lens in which light rays that enter it parallel to its axis cross one another at a single point on the opposite side with a converging effect

Answer 3

CONVEX LENS OR CONVERGING LENS

Question 4

A lens that causes the light rays to bend away from its axis

Answer 4

CONCAVE OR DIVERGING LENS

Question 5

its job is to turn light into signals about images that the brain can understand.

Answer 5

RETINA

Question 6

Acts like a window at the front of the eye.

Answer 6

CORNEA

Question 7

The amount of light entering the eye is controlled by the ?

Answer 7

PUPIL

Question 8

Colored part of the eye; surrounding the pupil

Answer 8

Iris

Question 9

cells responsible for daylight vision.

Answer 9

CONES

Question 10

are responsible for night vision. They are sensitive to light but not to color. In the darkness, the cones do not function at all.

Answer 10

RODS

Question 11

the failure of rays to converge at one focus because of limitations or defects in a lens or mirror

Answer 11

ABBERATIONS

Question 12

color distortion in an image viewed through a glass lens.

Answer 12

CHROMATIC ABERRATION

Question 13

an optical problem that occurs when all incoming light rays end up focusing at different points after passing through a spherical surface.

Answer 13

SPHERICAL ABERRATION

Question 14

Image formation by Concave Mirror:
- At Infinity
- Behind the center of curvature
- At the center of curvature and focus

Answer 14

At Infinity
- a real image is formed at the focus.
- inverted
- much smaller
Behind the center curvature
- real image is formed between the center of
- curvature and focus.
- Inverted
- smaller
At the center of curvature and focus
- real image is formed at the center of curvature.
- Inverted
- Same Size

Question 15

Image formed by Concave Mirror
- Between the center of curvature & focus
- At the focus
- Between Focus and pole

Answer 15

Between the center of curvature & focus,
- real image is formed behind the center of curvature.
- Inverted
- Bigger than object
At the Focus
- a real image is formed at infinity
- inverted
- much larger compare to the object
Between focus and pole
- virtual image is formed behind the mirror.
- Erect
- Larger

Question 16

Pag concave ang real image ay before sa salamin (or sa curve), ang virtual ay lagpas

Answer 16

Pag convex naman, ung virtual image mauuna bago ung salamin ( or ung curve)
