TRANSCRIPT
Opaque, Translucent, Transparent
• Opaque – only absorbs and reflects light• Translucent – allows some light to pass
through, some light absorbed and reflected• Transparent – allows almost all the light to
pass through, only a small amount of light absorbed and reflected
Law of Reflection• The angle at which a light wave strikes a
surface is the same as the angle at which it is reflected.
Refraction• Caused by a change in the speed of light
• If the light wave is traveling at an angle and the speed that light travels is different in the two materials the wave will be bent (refracted)
