Here's a breakdown:
* Transparent: Light passes through these materials with minimal scattering. We can see clearly through them. Examples include glass, water, and air.
* Translucent: Light passes through, but it is scattered, making objects appear blurry or hazy. Examples include frosted glass, parchment paper, and some types of plastic.
* Opaque: Light cannot pass through these materials at all. They absorb or reflect all the light that hits them. Examples include wood, metal, and brick.
