Plane Mirror
A plane mirror is a flat, smooth reflective surface—typically formed by depositing a thin layer of silver or aluminium on one side of a glass plate—that reflects light according to the laws of reflection to form virtual, upright, and laterally inverted images.
Importance in UPSCUPSC में महत्व
Essential microtopic under General Science (Physics - Optics) for UPSC Prelims testing foundational laws of reflection, image characteristics, magnification, and field of view, while serving as a baseline concept for advanced optical instruments and defence applications like periscopes.
Learning Outcomesसीखने के परिणाम
