Use the following information to answer the next three questions. A survey team uses 25.0 W lasers to map terrain. The laser is composed of three main parts: an energy source, an active medium, and an optical cavity. The optical cavity encloses the active medium and two mirrors. The active medium in the laser is a low-density heliumneon gas mixture. Energy source Reecting mirror Optical cavity Partly reflecting mirror 8. The 25.0 W laser is only 0.0200% efficient in converting electric energy into photon energy. The output power of the laser is A. 5.00 >
