Cannot know the position and the momentum of a quantum object with certainty/ precisely at the same time
1 of 9
Give an equation that represents the principle
delta_ x * delta_p >= h/4*pi ] where x is position and p is the momentum

Where does HUP originate from?
The intrinsic uncertainty of quantum systems as they exist as probability states (# fuzziness in nature)

Define the wave function (relating it to phi of an electron)
A mathematical description of the quantum state of a system which contains measurable quantities such as the electrons energy and its quantum numbers.

What is the Born rule?
The probability of a wave is proportional to its intensity. --> The magnitude of phi(x,t)^2 = intensity ; where phi(x,t) is the amplitude of the wave.

What is the probability density ?
phi^2 ] predicts where the particle (electrons) would be found

Name a significance of Schrodinger's equation?
If used to model the Hydrogen atom (energy levels) , the solutions mirror that from Bohr's equation. It allows also the visualisation of where the electron is most likely to be found.

Define Orbital
The region around the nucleus within which the probability of finding an electron is the maximum (not a specific position)

Summarise the Copenhagen interpretation
Matter exists in many states and its only when measurements are taken that matter becomes confined in one of these states. Thus, Quantum mechanics can only give probabilities of matter in these states.
