Study Notes
Laws of Reflection
- The incident ray, reflected ray, and the normal lie in the same plane at the point of incidence.
- The angle of incidence is equal to the angle of reflection.
Reflection in Plane Mirrors
- The image and object are equally far from the mirror.
- The image and the object are the same size.
- The image is virtual and cannot be captured on a surface.
- Real images can be captured on a surface.
- The image is laterally inverted.
- The image is upright.
Ray Diagrams
- Locate the image, I.
- Draw reflected rays.
- Draw incident rays.
Regular Reflection
- Parallel incident rays are reflected in the same direction due to a smooth surface.
- Results in a clear image because all rays have the same angles of incidence and reflection.
Irregular (Diffuse) Reflection
- Parallel incident rays are reflected in different directions due to a rough surface.
- Results in no clear image, due to the angles of incidence and reflection differing from one ray to another.

Description
The ray model represents light using straight lines to show its direction. Each line is a light ray, and a group of light rays together form a beam of light. This model helps visualize how light propagates.
