Convex and Concave Mirrors - a 3D simulation
This simulation demonstrates how concave and convex mirrors form images. It uses the mirror equation, $\frac{1}{f}=\frac{1}{d_o}+\frac{1}{d_i}$, where $f$ is the focal length,...

Thin Converging Lens 3D Simulation
Ever wondered how lenses form real and virtual images? Welcome to the Thin Converging Lens Simulation, your interactive 3D optics lab. Start by adjusting focal length, object...
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...
