Everything about Real Image totally explained
In
optics, a
real image is a representation of an actual object (source) formed by
rays of
light passing through the
image. If a screen is placed in the plane of a real image the image will generally become visible. The image seen on a
cinema screen is an example of a real image.
Real images can be produced by
concave mirrors and converging
lenses.
When we see through a lens, or look into a convex or concave mirror, what we see is
not a real image. This, the image that we see on the other side of the lens or mirror plane, is known as
virtual image.
Real rays of light are always represented by full, solid lines.
A real image occurs where rays converge, whereas a virtual image occurs where rays only
appear to converge.
A real image is exemplified by a science toy/demonstration called "Mirage" which consists of two facing
parabolic mirrors. One faces up, the other faces down one with a hole at its center. A real image of an object at the apex of the lower mirror appears just above the hole in the upper mirror.
