👉 The term "zentner" is a term used in physics and engineering, particularly in the field of electromagnetism. It describes a phenomenon where light travels through a medium at different speeds depending on its speed relative to that medium. In this context, it refers to the process by which light waves are refracted or bent when passing through a material with different refractive indices compared to the surrounding medium. This is known as refraction and is crucial in many applications of optics, such as telecommunications
