A hologram is a three-dimensional image created using light. It is made by recording the pattern of light waves reflected from an object and then reproducing this pattern so that it appears three-dimensional when viewed. Unlike a regular photo, a hologram can show different perspectives of the object, giving the illusion of depth and allowing the object to be viewed from different angles. Holograms are used in various fields, including art, technology, and security to prevent fake copies.
