The 3 ways that light behaves

Light waves interact with materials

Light can be reflected, transmitted, or

absorbed…but why?

It depends on whether the object is transparent, translucent or opaque

Transparent

Transparent materials allow light to pass through so that objects behind can be clearly seen.

Glass windows, glass doors, fish tanks, water, saran wrap

Translucent

Translucent materials transmit some light but cause it to spread in all directions

You can see light through these materials but not clearly

Lampshades, frosted glass, sheer fabrics, notebook paper

Opaque materials do not allow any light to pass through them

Construction paper,

Trees, Animals, Footballs

Opaque
