What is Hologram?
Light is an electromagnetic wave. Holography takes advantage of the fact that light is a wave. Unlike a traditional photograph, which uses a lens to focus an image on an electronic chip or a piece of film and simply records where there is light or no light, holography records the shape a light wave takes after it bounces off an object, similar to the impression left by pressing a key into clay. It uses interfering light waves to capture completely three-dimensional images. Light waves interact in the same way as water waves do when they encounter example — Water ripples when the stone hits the water surface of the pond.
