Simple steps to test if an object is transparent, translucent, or opaque

📚 Quick Study Guide

• 💡 Transparent: Allows light to pass through clearly, so objects behind it can be seen distinctly. Think of a window or clear glass.
• 🔍 Translucent: Allows some light to pass through, but objects behind it are not clearly visible. Examples include frosted glass or thin paper.
• 🧱 Opaque: Blocks light from passing through, so objects behind it cannot be seen at all. Wood, metal, and brick are opaque materials.
• 🧪 Testing: Simply hold the object up to a light source and observe how much light passes through and how clearly you can see objects behind it.
