- Real image
optics, a real image is a representation of an actual object (source) formed by rays of lightpassing through the image. If a screen is placed in the plane of a real image the image will generally become visible. Examples of real images include the image seen on a cinema screen, the image produced on a detector in the rear of a camera, and the image produced on a human retina.
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 a
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. [http://www.grand-illusions.com/acatalog/Mirage.html]
