Key Concepts

Law of Reflection

This principle in optics states that the angle of incidence is equal to the angle of reflection. It is a fundamental law governing how light rays behave when interacting with reflective surfaces and explains that the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

Angle of Incidence

This is the angle measured between the incident ray and an imaginary line called the normal, which is perpendicular to the surface at the point of contact. It defines how sharply a ray of light strikes a surface.

Angle of Reflection

This is the angle between the reflected ray and the normal. According to the law of reflection, it is precisely equal to the angle of incidence, ensuring that the incoming and outgoing paths of the ray are symmetric relative to the normal.

Normal

A line drawn perpendicular to the surface at the point of incidence. It serves as the reference line for measuring both the angle of incidence and the angle of reflection, facilitating the application of the law of reflection.
