in Trillium Lake.]]Reflection is the change in direction of a wave front at an interface between two differentmedia so that the wave front returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.ReflectionsReflection of light may be specular (that is, mirror-like) or diffuse (that is, not retaining the image, only the energy) depending on the nature of the interface. Furthermore, if the interface is between dielectric-con
