Question details

2. Consider the following retroreflector (a device that reflects light back to its source), which consists of two perpendicular mirrors. Prove that any ray incident on this retroreflector is reflected backward regardless of its incident angle. 3. The numerical aperture (NA) of an optical fiber is defined as NA-sin Cnax), where
