1. Series 9. Year - 2. semitransparent mirrors
We have two semitransparent mirrors, either of which transmits about 1/5 of light beam and reflects the rest (this in an experimental result). When we place both mirrors perpendicularly to the direction of a parallel light beam (see pic. 2), the first idea suggests that this system transmits just 1/25 of incident light. In fact it is much more, about 1/10. Explain this „paradox“!
