Light - Reflection (continued).
When you look into a mirror,
you see a reflection that is an image of the real object.
The image appears to be
the same distance behind the
mirror
as the real object is in front of it.
This is because the brain thinks that light travels in straight
lines
without changing direction.
The image is called virtual because the light rays
(shown
as dotted lines)
never really
go there
(compare this with a real
image).
The virtual image in a mirror
is the
same size as the object but with left and right reversed.
