Practical 9 Measuring the velocity of a wave by analysing a video
Introduction
Standing waves are not in the SL core so this makes it difficult to find a suitable waves practical, I decided to use a wave simulation in this instance since experimenting with traveling waves isn't easy, I also get to tick the "simulations box" in the ICT requirements. The main reason for doing this practical is to introduce the use of "LoggerPro" to analyse video, this is very useful when students design their own experiments.
In this practical students measure the speed of a wave in a string at a range of tensions, the results are not as expected!
Assessment
This practical is not used for assessment of any criteria
