Using flat mirrors ray diagram rules
How do we draw the ray diagram for a flat mirror, an object and an observer using flat mirror ray diagram rules? See below:
The first stage is to draw an image on the other side of the mirror perpendicular (at 90°) to the mirror.
Behind the mirror
The same size
|Object distance||`=`||Image distance|
You should end up with the following diagram:
The second stage is to draw rays from the eye to the top of the image and bottom of the image as follows:
The third stage is to join the light rays from the mirror to the object.
Notice how the image is.
SAME SIZE AS THE OBJECT
VIRTUAL (can not be shown on a screen)
AS FAR BEHIND THE MIRROR AS THE OBJECT IS IN FRONT.
