====== Light Demonstrations ===== Light is a form of electromagnetic radiation that makes vision possible and interacts with matter in distinctive ways. This category looks at how light travels, reflects, refracts, and disperses, as well as how it can be absorbed or transmitted. Studying light helps connect physics to everyday experiences and technologies, from seeing colours to using optical instruments.\\ ---- struct table ---- schema: demo cols: page, materials, difficulty, safety, summary header: "Demonstration", "Materials", "Difficulty", "Safety", "Summary" filter: categories~Light filter: page~demonstrations:% sort: title csv: 0 ---- **Materials**\\ ★☆☆ Easy to get from supermarket or hardware store\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires materials not commonly found in school laboratories\\ **Difficulty**\\ ★☆☆ Can be easily done by most teenagers\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires a more experienced teacher\\ **Safety**\\ ★☆☆ Minimal safety procedures required\\ ★★☆ Some safety precautions required to perform safely\\ ★★★ Only to be attempted with adequate safety procedures and trained staff\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\
