Peegelduvus

Peegelduvus refers to the phenomenon of light or other waves reflecting off a surface. When waves encounter a boundary between two different media, a portion of the energy can be reflected back into the original medium. The degree to which this reflection occurs depends on the properties of the surface and the incident waves, such as their angle of incidence and wavelength. In the case of light, the reflective quality of a surface determines how well it acts as a mirror. Smooth, polished surfaces, like those of mirrors, exhibit specular reflection, where incoming parallel rays are reflected as parallel rays. Rough surfaces, on the other hand, scatter light in many directions, a process known as diffuse reflection. Peegelduvus is a fundamental concept in optics and is crucial for understanding how we see objects and how optical instruments like telescopes and cameras function. It also plays a role in other wave phenomena, including sound reflection and radar. The law of reflection, a key principle governing specular reflection, states that the angle of incidence equals the angle of reflection, and that the incident ray, reflected ray, and the normal to the surface all lie in the same plane.
