Product Details

AP Physics 2, Big Idea 6, Investigation 14

In this advanced-inquiry investigation, students devise a method for measuring the width of very thin materials by taking advantage of the principles of diffraction. The introductory activity provides instructions for setting up an apparatus to create diffraction patterns by shining monochromatic red laser light at the edges of various materials. The guided-inquiry activity challenges students to devise a means for calculating the widths of the various materials and assessing experimental error. This lab is a great way help students develop their analytical thinking skills. 

Complete for 24 students working in groups of four. All materials are reusable.

Performance Expectations

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-3. Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
