You should perhaps acquaint yourself with the basics of raytracing.
There's an intro for example here: http://en.wikipedia.org/wiki/Ray_tracing
Backwards raytracing works by sending rays from the camera towards the
scene. When a ray hits a surface, its color is calculated (from various
parameters, such as the pigment, light sources, etc). If the surface is
reflective, a new ray is spawned from that point, which can hit other
surfaces.
A surface doesn't need a light source in order to contribute color to
the ray.
