← ScienceWhich mechanism causes increased dielectric heating when microwave frequencies match a molecule's rotational mode?
A)Resonant energy absorption✓
B)Increased wave reflection
C)Reduced power dissipation
D)Suppressed dipolar oscillation
💡 Explanation
Resonant energy absorption occurs because the electromagnetic field's frequency matches the molecule's natural rotational frequency, maximizing energy transfer through constructively interfering angular momentum; therefore absorption increases, rather than minimized reflection because frequencies cancel under different quantum selection rules.
