Refracted rays of light

Refraction will be especially interesting, if the boundary between the two materials is not straight but curved. In this case, every incident ray of light is refracted in a slightly different angle. With the following simulation you can try how the rays of light will be refracted, if they hit a glass globe filled with water (shoemaker's ball).

You will see, that the incident light is focussed onto a smaller area. Mainly observe when particularly a lot of light is bundled.
