Concave, Convex and Plane mirrors

What is the law of reflection

* The law of reflection states that the angle of reflection is always equal to the angle of incidence
* The incident ray, normal, and reflected ray all line on the same plane

What are the characteristics of an image?

1. Size: Larger, Smaller, the same?
2. Attitude: Upright or Upside down?
3. Location: Is the image in front of or behind the object
4. Type: Real or Virtual?

How can you tell if an image is real or virtual

* Real: The image and rays meet before the mirror
* Virtual: The image and rays meet behind the image

How can you tell if an image is upside down or upright?

* Upright: An upright image means the light rays meet before the mirror
* Upside down: Means the rays meet behind the mirror

What are the focal point and the focal length?

Focal Point: the point where light rays meet

Focal Length: The distance from the vertex to the focal point

Define these terms: Vertex, Principle axis, d0, di, ho, hi

* Vertex: Middle point of the mirror
* Principle Axis: Imaginary line drawn through the vertex
* do: Distance between the object and the vertex
* di: Distance between the vertex and the image
* ho: Height of the object
* hi: Height of the image

How do you calculate magnification?

M = di/ do
