Imagine you have a toy that can make two shadows on the wall, one from the front and one from the side. When they overlap, it looks like the toy is standing there in real life! That’s how holograms work. Instead of just one light source, they use many to create a 3D image that you can see from different angles.
Examples
- A hologram on a smartphone screen showing a live video of a concert from different angles.
