Application of the law of reflection in ray diagrams.

Description

Law of Reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection. This principle is illustrated in ray diagrams.

  1. a

    Describe how to construct a ray diagram to demonstrate the law of reflection.

    Aim for approximately 4 distinct marking points.

Description

Ray Diagram Components

In a ray diagram, light rays interact with a reflective surface. The normal line is drawn at the point of incidence, and angles are measured from this line.

  1. a

    Explain the significance of the normal line in ray diagrams.

    Aim for approximately 2 distinct marking points.
