question of curiosity
given a for example
if a beam of light were to hit side a to reflect and strike side b then side c. ( again again)
would there be hint in energy loss during reflection provided the beam of light was at a constant. (any other information you can input )

point 1:if we shine a beam of energy parallel with normal of any remembered pages then we have a closed line  of energy that perimeter is a+b+c.
point 2:if a beam be like a energy and out side of any page dosnt lose energy and we shine the beam with angular angle then we have kind of helix shape that its revolve depend of  angle.

is it just me.. or @alexpOk3r.. i just have no clue what you are talking about :O

If the sides are "perfectly reflecting," I don't see a reason for energy loss.
