Transparent objects allow light to pass through them easily, with little or no distortion. Some examples of transparent objects include glass, clear plastic, and water. Transparent objects are often used in windows, mirrors, and eyeglasses.

Translucent objects allow light to pass through them, but they scatter the light, making it difficult to see objects clearly. Some examples of translucent objects include tissue paper, frosted glass, and wax paper. Translucent objects are often used in lampshades, shower doors, and privacy screens.

Opaque objects do not allow light to pass through them at all. Some examples of opaque objects include metal, wood, and cardboard. Opaque objects are often used in walls, doors, and furniture.
