Mirrors

Question 1

Geometric optics

Answer 1

The science of how light reflects and bends

Question 2

Image

Answer 2

A reproduction of an object produced by an optical device

Question 3

Optical device

Answer 3

Any technology that uses light

Question 4

Normal

Answer 4

Dashed line drawn perpendicular to the mirror at the point of reflection represents an imaginary line

Question 5

Incident ray

Answer 5

Incoming ray

Question 6

Angle of incidence

Answer 6

The angle between the incident ray and the normal

Question 7

Angle of reflection

Answer 7

The angle between the reflected ray and normal

Question 8

Law of reflection

Answer 8

When light reflects off a surface the angle of incidence is always equal to the angle of reflection

Question 9

Plane mirror

Answer 9

Any mirror that has a flat reflective surface

Question 10

Virtual image

Answer 10

Any image formed by rays that do not actually pass through the location of the image

Question 11

Focal point

Answer 11

The point where light rays meet or appear to meet

Question 12

Vertex

Answer 12

The middle point of a curved mirror

Question 13

Focal length

Answer 13

The distance from the vertex to the focal point

Question 14

Real image

Answer 14

An image formed by light rays that converge at the location of the image

Question 15

Concave mirror

Answer 15

Converging mirror has a surface that curves inward like a bowl

Question 16

Solar oven

Answer 16

A device that uses light from the sun as its energy source

Question 17

Magnification

Answer 17

The measure of how much larger or smaller an image is compared with the object itself

Question 18

Convex mirror

Answer 18

A surface curved outward also called diverging mirror
