In diffuse reflection or scattering, light hitting the object from one direction is reflected in many directions. This gives the appearance of a matte surface. The rippled surface of wind-blown water will give a diffuse reflection. The Moon reflects light from the Sun in a diffuse way.

Diffuse reflection or scattering. Light shining on a rough object like sand or sandpaper reflects in many directions. The light travels in straight lines, but the surface is irregular, so the reflected rays bounce off small pieces of the surface that are tilted at different angles, and go off in many different directions.
