I'm working on a raytracer, and got stuck with trying to model a lens analytically.

Given is a thin lens at position p with the axis n, radius r and a focal distance f, a ray hits it at position p1 going in the direction d.

Which way would the ray be going on the other side of the...

Energy conservation.

I was really wondering, How physicists arrived to this law?

I was fine with it, solving problems and stuff. But sometimes things click in my mind.

Perhaps confusionleads to a better understanding...

We can prove mathematically...

Person A is carrying an electrostatic charge. They touch person B, both get a shock.

If both persons were off the ground(eg hanging from ropes) ...would they still get a shock?]]>
