I'm new to the field of quantum mechanics and I have got this basic doubt.(adsbygoogle = window.adsbygoogle || []).push({});

The position of the particle in a box is defined by the sine curve. Any position on a sine curve requires 2 coordinates to get the location of the particle having the highest probability at any point of time.

But why is it considered as single dimension ?

(The particle is free to move in the left or right direction, but as we define it by a sine curve it can also move up and down.)
