Lens Ray Diagram Simulation
I initially wanted to modify my GeoGebra applet on the converging lens ray diagram to include the case for infinitely far objects but thought I should give Claude.ai a try to...

Snell's Law Self-Assessment
My third applet today is a self-assessment tool for students to practise calculations with Snell's Law, i.e. $n_1 \sin{\theta_1} = n_2 \sin{\theta_2}$. The direct link to the...
Where is the Fish? A Refraction Simulation
I have seen a few simulations for apparent depth but was not satisfied with them. So I created this from scratch for use in tomorrow's lesson. The positions of the eye and image...
Reflection with a Plane Mirror
This applet allows for students to visualise the conditions under which a reflection can be seen in a mirror. When the mirror is too short, for instance, the point of reflection...

Invisible Spheres using Hydrogel
I used this demonstration to start a conversation about refractive index with my IP3 kids. These hydrogels certainly generated a lot of excitement as the kids were fascinated with...
