Specular Reflection

For a spherical surface is illuminated a region has bright spot which is white in color in a specific region. This reflection in the specified region is known as specular reflection.

Specular Reflection

Here, L = Unit vector directed towards light source

R= Unite vector in direction of ideal specular reflection

N= Unit normal vector

V= Unit vector pointing to viewer.

b= Viewing angle

For a perfect mirror, V and R coincides, i.e. a=b
