![]() This creates a smooth surface now and we observe specular reflection instead of diffuse reflection.Īns. Normally the light rays are diffused due to the rough surface of the road but when the road is wet, water fills the irregularities present on the surface of the road. We experience difficulty in driving at night on a wet road because of the glare caused due to lights of vehicles coming from the opposite direction. Similar to the above example, if a gust of wind disturbs the water surface, the resulting waves and ripples would cause diffuse reflection. A piece of paper may look smooth on the surface to the naked eye, but at the microscopic level, there are tiny fibres that make it rough. The light which reflects off the water surface exhibits specular reflection.ĭiffuse reflection occurs when reflected rays travel in multiple directions off rough surfaces. This too happens as a result of specular reflection. On a number of occasions, we have seen photographs in which the photographer captures the reflection of the object in water. Specular reflection occurs from a calm lake because the surface is so flat that all the reflected rays bounce off in the same direction. It also occurs because of other smooth surfaces like glossy tabletops, car windows, and still water surfaces. ![]() Specular reflection is most commonly known as the kind of reflection we get from a mirror. ![]() Read also: Reflection of Light by Spherical Mirrors ![]()
