🌈 Light Energy
Discover the science of light and how it shapes the world around us! This quiz explores light as a form of energy, its wave properties, and the visible spectrum. Learn how light interacts with matter through reflection, refraction, and absorption, and discover practical applications in mirrors, lenses, and shadows. **What you'll learn:** - Light travels as waves and carries energy - How light reflects, refracts, and is absorbed by different materials - The visible spectrum and why we see different colors - Natural and artificial light sources and their properties - Practical applications of light in everyday life
