Reflecting mirrors in laser is used to______________?
Correct answer: A. Further stimulation
- A. Further stimulation
- B. Lasing more
- C. For producing more energetic lasers
- D. AllIndustrial Materials & Equipment
Explanation
The mirrors in a laser cavity reflect photons back through the active medium, causing repeated stimulated emission and maintaining the laser beam. The likely wrong choice is lasing more, because the mirrors do not independently create laser energy; they provide optical feedback for further stimulation.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
