← ScienceWhich outcome arises when impurities disrupt a crystal's lattice?
A)Increased electrical resistance occurs✓
B)Enhanced thermal conductivity results
C)Greater optical transparency appears
D)Improved mechanical strength develops
💡 Explanation
Increased electrical resistance occurs because electron flow is impeded through disruption of the propagating wave via phonon scattering or similar *electron-phonon interaction*. Therefore, resistance increases rather than decreased conductivity, higher transmission, or greater strength under lattice disruption.
