Reflection of Light from a Concave Mirror.
When light is a reflected from a curved
mirror
the light rays change direction
in the same way that they do when they pass through a lens.
A convex mirror disperses
light like a concave lens
and a concave mirror focuses
light like a convex lens.
A concave mirror is used in a reflecting telescope.
Parallel rays of
light
(or other electromagnetic
rays) are
brought to a focus by the concave
mirror to form a real
image.
