3.16 construct ray diagrams to illustrate the formation of a virtual image in a plane mirror

When light rays bounce off an object onto a mirror, a virtual image is formed. A ray diagram shows how this image is produced (in a plane mirror)

Method

- firstly, draw a line from the top of the object to the reflective surface (in this example it is a lake, although it could be a mirror/shiney surface etc)
- reflect the incidence engle in the reflective surface and draw the reflective
 (into a human eye_
- now continue the ray from the eye through the reflective surface until it is in line with the real image.
- repeat with a line from the bottom of the real image.
- the lines will now show where the top and bottom of the virtual image are, just fill in by drawing in the image.


(sorry that was a little confusing)
