... F. Why does it matter that an electron behaves as both particle and wave? 1) The fact that electrons behave as waves leads to some odd observations, like: 2) Heisenberg’s uncertainty principle- it is impossible to know exactly both the of a particle at the same time. a. This limitation is critical i ...
