What is hologram?

Holography

When an entity is photographed by a camera a two dimensional image of three dimensional objects is obtained. A three dimensional image of an object is able to be formed by holography.

In normal photography the amplitude of the light wave is recorded on the photographic film. In holography both the phase as well as amplitude of the light waves is recorded on the film. The resultant photograph is called hologram.
