Have you ever wondered about those magical glasses that turn black in sunlight automatically? Well, they're made of something called photochromic glass! Let's dive into the science behind the Glasses which turn black under sunlight. Science behind Photochromic Glasses Let's break down the working of photochromic glass into simple steps: Exposure to Light: The process starts when photochromic glass is exposed to light, particularly ultraviolet (UV) radiation or sunlight. These are the types of light that trigger the photochromic reaction which takes place by using energy provided by sunlight. Activation of Photochromic Molecules: Within the photochromic glass, there are special molecules known as photochromic molecules. When these molecules absorb UV light, they undergo a chemical reaction that causes them to change their structure temporarily, which causes change in the physical properties of molecules. Color Change: As a result of the chemical reaction, the photochromic m...
