The Uncertainty Calculator (Heisenberg's Principle) will calculate the:

- One of uncertainties among that of particle's position and momentum when the other uncertainty is known
- One of uncertainties among that of particle's energy and time interval in which it possesses that energy when the other uncertainty is known

**Calculation Parameters:** Medium of propagation is assumed as vacuum
