Theories of Image Formation

Theories of image formation describe how images are created when light interacts with objects and is captured by a device like the eye or camera. The primary theories are the **geometric theory**, which explains images based on light rays and angles, similar to how a camera focuses light through lenses to form an image. The **wave theory** considers light as waves, explaining phenomena like diffraction and interference. The **quantum theory** views light as particles called photons, crucial for understanding how devices detect very faint light. Together, these theories help us understand how we see and how cameras and microscopes produce images.
