← ScienceWhich outcome occurs when a quantum mechanical wavefunction's superposition collapses?
A)Definite observable property is realized✓
B)Quantum entanglement correlation increases
C)Uncertainty in position always increases
D)Wave function's energy expectation increases
💡 Explanation
When superposition ends, decoherence via quantum measurement causes wave function collapse, because interactions with the environment force the system into a single eigenstate; therefore, a definite value appears, rather than the persistence of multiple probabilities in superposition.
