← ScienceWhich risk increases when laser light excites an electron orbital?
A)Photochemical induced material degradation✓
B)Reduced thermal conduction capacity
C)Increased compressive mechanical stress
D)Enhanced electrical insulation breakdown
💡 Explanation
Photochemical degradation risk rises because photoexcitation causes a **bond dissociation** mechanism, breaking chemical bonds, therefore the material degrades rather than exhibiting increased thermal or electrical resistance which require different conditions.
