Why do clothes get wet?

Why do clothes get wet? When light strikes any surface, some of it is reflected back into our eyes. But damp clothes have a thin layer of water on their surface (held in place by the material’s roughness), which leads to more of the reflected light rays being bent – ‘refracted’ – off-course. When a […]
