heijastuslaki
Heijastuslaki, often translated as the law of reflection, is a fundamental principle in optics that describes how light bounces off a surface. It states that the angle of incidence is equal to the angle of reflection. The angle of incidence is the angle between the incoming ray of light, known as the incident ray, and the normal, which is an imaginary line perpendicular to the surface at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray of light and the normal.
Furthermore, the law of reflection dictates that the incident ray, the reflected ray, and the normal all
