Light Rays

4. of Incidence The angle measured between the incident ray and the normal.
5. A narrow beam of light that travels in a straight line from its source.
6. of Reflection The angle measured between the reflected ray and the normal.
7. Ray A light ray that bends as it passes at an angle from one transparent medium into another.
9. Ray The incoming light ray that strikes a surface or boundary.
10. An imaginary line drawn exactly perpendicular to the surface where a light ray strikes.

1. Rays Light rays that bend or travel toward each other, eventually meeting at a single point.
2. Tracing A modeling method used by physicists and software to map the paths of light rays as they interact with surfaces.
3. Ray The light ray that bounces back after hitting a reflective surface, like a mirror.
8. Rays Light rays that spread outward and separate from a single source or focus point.
11. of Reflection The principle stating that the angle of incidence exactly equals the angle of reflection.
