← ScienceWhich outcome occurs in double-slit experiment when observation collapses electron's wave function?
A)Interference pattern disappears completely✓
B)Wavelength shifts toward higher energy
C)Velocity increases due to potential change
D)Coherence between slits maintains pattern
💡 Explanation
When an observation is made, the wave function collapses because the electron's quantum state is forced into a definite position, preventing its propagation as multiple interfering waves. Therefore, the interference pattern disappears, rather than wavelength/velocity changes, coherence as the wave nature collapses into a particle.
