Grade Level: 9th - 12th; Type: Holography
Demonstrate and explain holographic technology.
The goals of this project are:
- To find out if a holographic image of a magnifier still magnifies.
- To illustrate and explain the effect.
- What is a hologram?
- How do holograms work?
- Does a holographic image of a magnifying glass still magnify?
Holographic images have captured our collective fascination since the early 1960s. They are used for purposes like security, data storage and artwork. It is said that if you make a holographic image of a magnifying glass, the image alone will still provide a magnified view of the object beneath it. In this project you will discover the truth behind the claim.
