Types of Reflection

  • Technology > Types of Reflection

Specular Reflection

  • Specular reflection is the mirror-like reflection of light from a surface, in which light from a single incoming direction (a ray) is reflected into a single outgoing direction.

Diffuse Reflection

  • Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection.


  • Retro-reflection is the reflection that reflects light back to its source with a minimum of scattering.
