That sir is where you are wrong. There are very well defined methods
that have been developed to define the characteristics of light and
how it interacts with various surfaces and finishes. Many of these
methods are used at least in part for metalurgical testing and there is
still a growing research industry for controlling laser light, either
through optimizing the reflection for a surface without loss of
energy or the multitude of of beam splitting surfaces whose applications
are so numerous that a degree from college on the subject will still
leave you not knowing everything you could know about it.
