👉 In physics and telecommunications, backscattering occurs when an electromagnetic wave is reflected off a surface or medium that is not parallel to its original direction. This phenomenon can occur in both dielectric and conductive media, such as air, glass, or metal. When light travels through a material with a high index of refraction (a material that has the same speed of light as water at 273 K), it will be scattered back towards the source, causing a reflection. This phenomenon is
