Refraction of Light: Forensic Lab

This lesson uses forensic science investigations to help students understand the refraction of light.  It first provides an excellent analogy to understanding the cause of light refraction. The forensic portion of the lesson has students solve a crime scene by identifying glass using the index of refraction.  Students also learn that the refraction of light occurs at the nanoscale as the visible light range is 380 to 740 nm.
