Double monochromater
Example
[p,q] = iħ
So p the momentum and q the coordinate of a quantum system may not be measured precisely simultanoesly
From this we deduce Heisenberg’s Uncertainty Principle
∆p∆q ~ ħ
and
∆E∆t ~ ħ
Which indicates that we can measure the energy of a molecule but when it had that energy
