← ScienceWhich outcome occurs when measuring the spin of one photon in an entangled pair over long distances?
A)Instantaneous knowledge of second photon's spin✓
B)Gradual collapse of wave function of both
C)Signal delay proportional to distance squared
D)Random spin alignment independent of distance
💡 Explanation
When measuring the spin of one entangled photon, quantum entanglement causes its entangled partner to instantaneously assume the opposite spin, regardless of the distance between them because their wave functions are correlated. Therefore, instant determination of second photon’s spin is immediate, rather than gradual collapse, signal delay, or random behavior which violate entanglement principles.
