... It is also useful to define the concept of equipotential lines and surfaces. A point charge can be moved without doing any work along an equipotential line (in 2 dimensions) or along an equipotential surface (in 3 dimensions). If no work is done, then the potential must be the same everywhere. Clear ...

A more scientific view is that we see things because light comes from them to our eyes. But only a few things generate their own light. Before the middle o ...
