# The Fascinating World of Mirrors
Mirrors are more than just reflective surfaces—they play a vital role in daily life, science, and art. Made by coating glass with a thin layer of metal, usually aluminum or silver, mirrors create clear reflections by bouncing light back to the viewer.
## Uses of Mirrors
– Personal Grooming: Essential in bathrooms and dressing rooms.
– Safety & Transportation: Used in vehicles (rearview and side mirrors) and surveillance systems.
– Science & Technology: Key in telescopes, microscopes, and lasers.
– Decor & Illusion: Enhance spaces by creating depth and light in interior design.
## Fun Facts
– The earliest mirrors, dating back to 6000 BCE, were made from polished obsidian.
– Mirrors can reflect both light and sound (used in auditoriums).
– A “two-way mirror” reflects light on one side while allowing visibility from the other.
From ancient tools to modern innovations, mirrors continue to reflect human ingenuity in surprising ways.
