Spegelreflektion

Spegelreflektion, often referred to as specular reflection, is a type of reflection in which light reflects off a surface in a single, predictable direction. This occurs when the surface is smooth, such as a mirror or polished metal. In specular reflection, the angle of incidence, which is the angle between the incoming light ray and the normal (a line perpendicular to the surface), is equal to the angle of reflection, the angle between the reflected light ray and the normal. This principle is known as the law of reflection. The reflected rays are parallel to each other, allowing for the formation of clear images. Examples of spegelreflektion are abundant in everyday life, from seeing your reflection in a bathroom mirror to the glint of sunlight off a car window. In contrast to diffuse reflection, where light scatters in many directions due to a rough surface, spegelreflektion is characterized by its orderly and mirror-like behavior. Understanding spegelreflektion is fundamental in fields like optics, photography, and the design of optical instruments.
