Flat Mirrors
A smooth reflecting plane surface
image of objects produced behind the mirror
same size, and same distance from the mirror
image has a definite location in space
determining the position of the image
- seeing is a passive activity
- our eye-brain system records only the direction from which the light arrives
main method: determining where the reflected light rays coming from different points of the object intersect
if the reflected light rays really intersect --> real image
if only the inverse direction continuation of light rays intersect
