Most objects produce diffuse reflections as light scatters off their surfaces in random directions. It is often almost impossible to pick out the shape or colour of objects in a diffuse refection.
- All objects obey the law of reflection on a microscopic level.
- If the irregularities on the surface of an object are larger than the wavelengths of the incident light, light reflects in all directions and produces diffuse reflections.
- A diffuse reflection is easily distinguished from the mirror-like qualities of a specular reflection.
About specular reflection
- Specular reflection, or regular reflection, is the mirror-like reflection of light from a surface in which everything appears as clearly as when viewed directly.
- Specular reflection occurs when the irregularities on the surface of an object are smaller than the wavelengths of the incident light.
