1. Refraction of Light: Forensics Lab

   06 Jan 2020 | | Contributor(s):: Karen Porter-Davis, NNCI Nano

   This lesson uses forensic science investigations to help students understand the refraction of light. Using The Marching Band Analogy, the students firsts “experience” how wavelengths of light can slow and bend.

2. Light Extraction by Changing Composition of Material

   06 Jan 2020 | | Contributor(s):: Sidhu Rano, NNCI Nano

   This activity has been designed to have students explore light emitting diodes (LED) and the importance of index of refraction in improving LED efficiency. This activity investigates the tune-ability of a polymer’s index of refraction by using a macromodel LED.

3. PhotonicsDB: Optical Constants

   14 Dec 2007 | | Contributor(s):: Xingjie Ni, Zhengtong Liu, Alexander V. Kildishev

   Experimental data is used to interpolate the dielectric function or the index of refraction of bulk materials used in optics and photonics
