# How can an electron have a node?

Aug 22, 2017

Well, an electron has wave-like properties.......

#### Explanation:

And a node is a point on a wave-function of MINIMUM displacement.

The nodes on the given wave-function (a sine wave), $\psi$, are at ${0}^{\circ}$, ${180}^{\circ}$, and ${360}^{\circ}$ etc. The physical significance of the wave-function of an electron is that its square, ${\psi}^{2} = \text{the probability of finding the particle}$. (You will have to read your text for the Born approximation! And that's Max Born not Jason Bourne).
