lysrefleksion
Lysrefleksion, often simply called reflection, is the phenomenon where light bounces off a surface. When light strikes a smooth surface, like a mirror, it reflects in a predictable manner. The angle at which the light hits the surface, known as the angle of incidence, is equal to the angle at which it bounces off, called the angle of reflection. This principle is known as the law of reflection. Different materials reflect light differently. Shiny surfaces, like polished metal, reflect most of the light that hits them, creating a clear image. Rough surfaces, such as a wall painted with matte paint, scatter light in many directions, making it difficult to see a distinct reflection. The color of an object is determined by the wavelengths of light it reflects. For example, a red apple appears red because it absorbs most colors of light and reflects red light. This process is fundamental to how we perceive the world around us, allowing us to see objects, read text, and navigate our environment. Understanding lysrefleksion is crucial in fields like optics, astronomy, and the design of optical instruments.
