What will light do in the following 3 situations? Created by KBuckner for Fried or Slide PBL 2010

Light travels in a straight line But when it hits an object it can do 1 of 3 things….it can 1) be reflected Created by KBuckner for Fried or Slide PBL 2010

Light travels in a straight line But when it hits an object it can 2) be transmitted (pass through) Created by KBuckner for Fried or Slide PBL 2010

Light travels in a straight line But when it hits an object it can 3) be absorbed Created by KBuckner for Fried or Slide PBL 2010

Absorption Absorption is the disappearance of an EM wave into the medium Absorption can cast shadows Created by KBuckner for Fried or Slide PBL 2010

The 3 ways that light behaves Created by KBuckner for Fried or Slide PBL 2010

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 Created by KBuckner for Fried or Slide PBL 2010

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 Created by KBuckner for Fried or Slide PBL 2010

OPAQUE Opaque materials do not allow any light to pass through them Construction paper, Trees, Animals Created by KBuckner for Fried or Slide PBL 2010
