6. TRANSPARENT MATERIALS
• material that allows most of the light to
pass through, or transmit light.
• Light easily pass through in this kind of
material without being scattered.
7. TRANSLUCENT MATERIALS
• Material may also allow some light to
pass through it, but as the light passes
through, the material scatters the light
rays.
• Can see something behind a
translucent material but it may appear
blurred and it may be quite difficult to
see the details.
