← ScienceWhat outcome happens when microwave frequency is precisely tuned to water molecule vibration in a food product?
A)Food undergoes differential heating✓
B)Magnetron tube experiences voltage spike
C)Waveguide suffers standing wave losses
D)Turntable motor shows angular oscillations
💡 Explanation
When microwave frequency matches water resonance, dielectric heating through molecular vibration happens efficiently because resonant absorption transfers electromagnetic energy to kinetic energy, increasing temperature substantially. Therefore food undergoes rapid differential heating, as opposed to alternative losses or anomalies away from resonance.
