You can use light rays and the laws of reflection to show how a plane mirror produces a virtual image and where it is located.

Normal - the perpendicular line to the mirror surface
Incident Ray - the original incoming ray
Angle of Incidence - the angle between the incident ray and the normal
Reflected Ray - the ray that bounces off a reflective surface
Monday, May 23, 16
The Laws of Reflection
1. The Angle of Incidence equals the Angle of Reflection
2. The incident rays, the reflected ray and the normal all lie in the same plane

Specular reflection - reflection of light off a smooth surface
Diffuse reflection - reflection of light off an irregular or dull surface

Draw the light rays behind the mirror as dashes because the light rays do not really exist.

MirrorsSo, why is the word ambulance written
backwards on the vehicle?

What is an Image?
A copy of an object through the use of light

Four characteristics of an image
Four characteristics of an image (S.A.L.T.):1.Size - The size of the image seen compared to the original object. (e.g., bigger, smaller, same)

Four characteristics of an image
2. Attitude - Orientation of the image seen compared to the original object. (e.g., upright, inverted)

Four characteristics of an image
3. Location (e.g., front of mirror, behind mirror, and how far from mirror)

Four characteristics of an image
4. Type (e.g., real or virtual)

Types of Images
Real image – an image that is formed when reflected rays meet
can be seen on a screen due to light rays arriving at the image location (e.g., movie screen)
Monday, May 23, 16
Types of ImagesVirtual image –an image formed by rays that appear to be coming from a certain position, but are not actually coming from this position
imaginedcannot form a visible projection on screen (e.g., plane mirror)
