Phase Difference
The first of two apps on Phase Difference allows for interaction to demonstrate the oscillation of two different particles along the same wave with a variable phase difference....
10 Wave Motion
Longitudinal and Transverse Waves
I modified Tom Walsh's original GeoGebra app to add a moveable single oscillating particle for students to observe its movement along a longitudinal wave and a transverse wave....
Movement of Particle in a Wave
This GeoGebra app allows students to observe closely the movement of a particle in a progressive wave, with two possible directions of energy propagation. In a typical question,...
Phase Difference GeoGebra Apps
I created a series of GeoGebra apps for the JC topics of Waves and Superposition, mainly on the concept of Phase Difference. The sizes of these GeoGebra apps are optimised for...
Wavefront
In order to help students visualise a wavefront, a 3-D image is usually used to show the imaginary line joining particles in phase. I created the GeoGebra apps below to allow...
Graphs of a Progressive Wave - Geogebra App
GeoGebra link: https://www.geogebra.org/m/f7faw3r6 This simple Geogebra app allows students to observe the oscillation of a particle perpendicular to the direction of energy...
Velocity of a Wave - Simulation
Try using the values in this simulation to find the velocity of this wave! Let me have your answer in the comment section! Update on 21 August 2018: The latest iteration of this...
Geogebra Simulation for Particle on a Transverse Wave
I am once again exploring the use of Geogebra to create simulations for Physics. This is what I managed to put together. It serves to help students visualise how a particle in a...
Measuring speed of sound in air using Audacity
A physics demonstration on how to measure the speed of sound in air using Audacity , an open source audio recording software. There are Windows and Mac versions of this free...
Phase Difference Simulation
I created this simulation for use later this semester with my IP4 classes, to illustrate the concept of phase difference between two oscillating particles....
Fun Experiments on Stationary Waves in Sound
Polarization with 3 Filters
In what seems like a counter-intuitive demonstration, we can place a polarizing filter in between two other filters which do not transmit light in order to cause light to pass...
Polarization Using Sunglasses and a Computer Screen
Using a pair of polarizing sunglasses, you can demonstrate the effects of polarization together with a computer screen which is also polarizing. When the axes of polarization of...
Learning about Sound with Audacity
Audacity is a free audio recording and editing software downloadable from http://audacity.sourceforge.net . It is cross-platform meaning you can run it on PC or Mac. Once you have...
