    • Enjoy the fun of physics with simulations
The following use ray tracing to find image for a point light source in a glass filled with water.
The refraction of water is assume to be 4/3 and the index refraction of glass is assumed to be 3/2.
Both of them can be modified with the sliders (index1 and index2).
yc is the location of the point source.

Click play (right triangle) to start the ray tracing.
You can drag the eye to find image at different viewing location. (Yes. it is depends on where you look at it).
