Types of surfaces1

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.

Types of Surfaces

Transparent:

Light goes through these surfaces almost completely. A small amount of light is reflected.

Examples: clear glass, air, water.

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.


Types of surfaces cont d1

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.

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.
