This simulator shows students what conditions are necessary for stationary waves to form. Various quantities can be adjusted to see whether stationary waves form or not. All of my drills are fully Excel compatible spreadsheets. This one is a simulation, which can be used to investigate the conditions for stationary waves to form.

This spreadsheet generates worksheets where students are shown rays and given refractive indices, then are asked what happens to the ray next (either refraction or total internal reflection). All of my drills are fully Excel compatible spreadsheets. This one is a worksheet generator, which can be used to generate an unlimited number of unique questions. Just press F9 (PC) or Cmd+= (Mac) to refresh the spreadsheet and generate a new question.

In this presentation, each slide is a single lesson. I have found that pupils really benefited from having the information condensed onto a single slide and displayed throughout the lesson whilst they were doing question practice. The slides are densely packed with information, images and animations to help make the topics clear. The order presented here is the same as the OUP AQA Physics GCSE Third Edition textbook, by Jim Breithaupt. I’ve included a pdf in case different versions of PowerPoint scramble things, but the animations will not work for the pdf. The animations work fine on PowerPoint.
