Law of Reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection. This means that when a ray of light hits a surface and is reflected, the angle at which it hits the surface is equal to the angle at which it bounces off the surface.

Key Concepts:

1. Angle of Incidence: The angle between the incident ray and the normal (a line perpendicular to the surface) at the point of incidence.
2. Angle of Reflection: The angle between the reflected ray and the normal at the point of reflection.
3. Normal: A line that is perpendicular to the surface at the point of incidence.

Study Guide:

Here are some key points to remember about the law of reflection:

• When a ray of light hits a smooth surface, it bounces off at the same angle it hit the surface.
• The incident ray, the normal, and the reflected ray all lie in the same plane.
• Reflection occurs for all types of waves, not just light waves.

Remember to practice using the law of reflection to solve problems involving the angles of incidence and reflection. Understanding this concept is important for understanding how we see objects and images in mirrors!
