2. What is an Image
When your eyes detect reflected light from a plane mirror, your brain projects these light rays backwards in a straight line. This results in your brain thinking that there is a light source behind the mirror and that is where the light rays originate.

3. Virtual Image
A virtual image is an image in which light does not actually arrive at or come from the image location.

4. Using S.A.L.T. to Describe the Image
S: size of the image (compared to the object)
A: attitude of the image (which way is the image oriented in comparison to the objects)
L: location
T: type of image (real or virtual)
