Science

Which outcome occurs when a microwave oven door's Faraday cage has gaps exceeding the wavelength of the microwaves?

A)Constructive interference forms hot spots
B)Magnetron lifespan is significantly extended
C)Eddy currents dissipate energy harmlessly
D)Waveguides optimally channel microwave energy

💡 Explanation

Increased microwave leakage occurs because diffraction allows waves through gaps; the **Huygens' Principle** dictates wave propagation originates from each point rather than direct blockage. Therefore, radiation escapes, rather than enhanced magnetron performance or waveguide behavior.
