This lab, presented by the National Nanotechnology Infrastructure Network, allows students to "understand how light is bent into different directions as it interacts with small objects, especially those on the nanoscale (1-100nm)." Additionally, students will learn about the process of x-ray defraction which allows scientists to see structures that are too small to see with the naked eye, including atoms, molecules, and crystal structures. In this lab, will create and explore their own diffraction gratings with a series of worksheets. Included in this lab are: Student Worksheet 1 Laser Box with answers, Student Worksheet 2 Interference Patterns with answers, Student Worksheet 3 Grating with answers, Student Worksheet 1 Laser Box, Student Worksheet 2 Interference Patterns, Student Worksheet 3 Grating, and Handout to make grating.
