An object is placed in front of a plane mirror.
Find the location and
characteristics of the image.
As shown above, we usually take the (extreme) top point and find its corresponding point on the image object.
There are two steps in finding the image of a plane mirror.
Draw an incident ray slightly downwards towards the
mirror, then draw its reflected ray.
we can select any arbitrary location.
Where the two reflected rays meet is the image point of the object point.
