the image formed from an opposing flat mirrors are progressively
smaller because, the distance between the two images formed are further apart,
each time a new image is formed the lat image is is two times further away from
it, in a plane mirror the object
distance and image distance are equal,
each time a new image is formed , its therefore two times away from the
last image formed,
object further away appear smaller than those that are closer , sun and star in
the “ sky” appear smaller ; like a ball but in reality they are bigger than the
earth.
