Measuring an Electron Spin
Classical Mechanics
Level
2
A electron spin in quantum mechanics is given by the superposition state:
\[\large |\Psi\rangle = \frac{i}{2} |\uparrow\rangle + \dfrac{\sqrt{3}}{2} |\downarrow\rangle.\]
What is the probability of measuring the spin in the \(z\)-direction to have value equal to \(-\dfrac{\hbar}{2}\)?
