1. Types of Surfaces

2. When light hits different surfaces, it behaves in different ways. Surfaces can be one of three types. Light can pass through a substance, bounce off a substance or do both partially.

5. Transparent

6. Translucent

8. Opaque

9. Types of Surfaces Transparent: Light goes through these surfaces almost completely. A small amount of light is reflected. Examples: clear glass, air, water.

10. Types of Surfaces (cont’d) Translucent: Light goes through these surfaces only partially. A certain amount is absorbed. Some light is reflected. Examples: frosted glass, wax paper, thin cloth.

11. Types of Surfaces (cont’d) Opaque (rough and dark): Most of the light is absorbed. A small amount of light is reflected in multiple directions (diffuse reflection). Examples: black wall, dark brick, dark book bag.

12. Types of Surfaces (cont’d) Opaque (smooth or pale): A small amount of light is absorbed. Most of the light is reflected (specular reflection). Examples: white wall, mirror.
