What is holography?
Q: What is holography?
A: Holography is a technique used to create 3-D images with lasers.
Q: How is holography different from photography?
A: Holography produces a more accurate 3-D image than photography.
Q: What makes a holograph appear three-dimensional?
A: The holograph appears three-dimensional because it seems to move and change slightly.
Q: What does holography use for its operation?
A: Holography uses the wave aspect of light for its operation.
Q: How is a holograph made?
A: A holograph is made by using a laser to record the interaction of two beams of light.
Q: Can a holograph be viewed without special equipment?
A: No, special equipment such as a holographic viewer or a laser pointer is required to view a holograph.
Q: What are some advantages of using holography over other imaging techniques?
A: Holography produces a more accurate 3-D image and allows for the manipulation of the image.
