catoptrics
Quick Summary
Catoptrics is a branch of optics that deals with the reflection of light and the properties of mirrors. It is concerned with how light rays change direction when they bounce off a surface.12
Key principles include:
* Law of Reflection: The angle at which light hits a surface (incident ray) is equal to the angle at which it bounces off (reflected ray).2
* Mirror Images: This law helps explain the images formed by both flat and curved mirrors.2
* Diffuse Reflection: Most natural surfaces are rough, causing light to scatter in many directions, allowing us to see objects from various viewpoints.2
Catoptrics is fundamental to understanding optical instruments like cameras and telescopes, which rely on the principles of light reflection.2
