Types of Surfaces. Types of Surfaces. 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. Transparent. Translucent. Translucent. Opaque. Types of Surfaces.
Types of Surfaces
Light goes through these surfaces almost completely. A small amount of light is reflected.
Examples: clear glass, air, water.
Light goes through these surfaces only partially. A certain amount is absorbed. Some light is reflected.
Examples: frosted glass, wax paper, thin cloth.
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.
Opaque (smooth or pale):
A small amount of light is absorbed. Most of the light is reflected (specular reflection).
Examples: white wall, mirror.
