1. What will light do in the following 3 situations?

2. Light travels in a straight line But when it hits an object it can do 1 of 3 things….it can… 1) be reflected

3. Light travels in a straight line But when it hits an object it can… 2) be transmitted (pass through)

4. Light travels in a straight line But when it hits an object it can… 3) be absorbed

5. Absorption Absorption is the disappearance of an EM wave into the medium Absorption can cast shadows

6. The 3 ways that light behaves

7. Light waves interact with materials Light can be reflected, transmitted, or absorbed…but why?

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

9. 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

10. 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

11. Opaque materials do not allow any light to pass through them Construction paper, Trees, Animals, Footballs Opaque
