Here's why:
* Transparent substances allow light to pass through them completely, so you can see through them clearly (e.g., glass, water).
* Translucent substances allow some light to pass through, but scatter it, making objects behind them appear blurry (e.g., frosted glass, thin paper).
* Opaque substances block all light from passing through, so you cannot see through them (e.g., wood, metal, a thick wall).
