THIS is the third part of a course of practical physics, the two previous ones dealing with heat and general physics. A fourth part, on electricity and magnetism, will complete the work. The optical ...

Light bends when travelling through a concentration gradient of sugar in water. The top layer of liquid is pure water while the bottom layer is concentrated sugar water. In these layers, there is no ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways.
