Which of the following light phenomena take place in a periscope?
WebA periscope is a useful example of the law of reflection at work. It's important that your mirrors are placed at a 45° angle because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. Important Points Web18. jan 2024 · Moth’s eye nanostructures that provide gradual refractive index changes from the structure's surface to the interface minimize reflections well over a wide range of wavelengths and incident ...
