Rugosity

Rugosity is like feeling the bumpy textures of a rock or a rough surface with your hands. Imagine running your hands over a bumpy road with little hills and valleys. The more hills and valleys you feel, the higher the rugosity. Scientists use it to measure how bumpy or rough a surface is. They use special tools to measure the height of these hills and valleys and calculate an average value. So when someone talks about rugosity, they are talking about how rough or bumpy a surface is by measuring the height differences in its texture.
