Holograms are three-dimensional images created using laser light. They capture the light scattered from an object and record it on a special surface, allowing the image to appear as if it is floating in space. When viewed from different angles, holograms can show depth and detail, making them distinct from regular photographs. These images are often used in various fields, including art, security, and medical imaging. For example, holograms can be found on credit cards to prevent counterfeiting, and they are also used in virtual reality applications to enhance user experiences.
