Q

What is Phosphorenscence?

Q

What does Laser stand for?

A

17
Q

What is a light ray?

A

A line and arrow representing the direction and path that light is traveling

18
Q

What is geometric optics?

A

The use of light rays to determine how light behaves when it strikes an object

19
Q

Reflection is…

A

the bouncing back of light from a surface

20
Q

What is a normal?

A

A perpendicular (right angles) to the reflecting mirror surface

21
Q

What is the angle of incidence?

A

The angle between the incident ray and the normal

22
Q

What is the angle of reflection?

A

The angle between the reflected ray and the normal

23
Q

What are the two laws of reflection?

A
  1. The angle of incidence equals the angle of reflection
  2. The incident ray, reflected ray, and the normal all lie in the same plane
24
Q

Reflection off of a smooth, shiny, surface is…

A

Specular reflection

25
Q

Reflection off of an irregular surface is…

A

Diffuse reflection

26
Q

What is a virtual image?

A

Virtual image - the reflection of an object that appears to be located behind the mirror but is not actually there

27
Q

What is lateral inversion?

A

Lateral inversion - refers to the fact that the orientation of an image in a plane mirror is backwards (flipped horizontally) and in reverse order

28
Q

What is SALT?

A

S - Size (same, smaller, larger)
A - Attitude (upright or inverted)
L - Location (behind : plane)
T - Type (real or virtual)

29
Q

What is concave and convex…

A

Concave - middle presses away
Convex - middle bulges towards

30
Q

What is a concave mirror also called…

A

Concave mirror is also called a converging mirror because it focuses the parallel rays at F.

31
Q

What is the vertex?

A

Vertex - where the principal axis intersects the mirror

32
Q

What is the principle axis?

A

Principle Axis - the line that goes through the centre of curvature

33
Q

What is the centre of curvation?

A

Centre of curvature (C) - the centre of the sphere whose surface forms the mirror

34
Q

When is no image formed…

A

When the object is located at F

35
Q

What are the characteristics of an image in a convex mirror?

A

Convex Mirror Image Characteristics
- smaller
- upright
- virtual image

36
Q

When is a makeup mirror work?

A

If the object is located inside F

37
Q

If a light ray is through the C, what would happen?

A

It would reflect back onto itself

38
Q

What will happen to a light ray through the focus?

A

It will reflect parallel to the principle axis
