Specular reflection
Videos
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.
Reflections on still water are an example of specular reflection.

Fresnel equations

The Fresnel equations describe the reflection and transmission of light when incident on an interface between different optical media. They were deduced by French engineer and physicist Augustin-Jean
Specular reflection
…and its angle of incidence. In general, reflection increases with increasing angle of incidence, and with increasing absorptivity at the boundary. The Fresnel equations describe the physics at the optical boundary. Reflection may occur as specular, or mirror-like, reflection and diffuse reflection. Specular reflection…
