← ScienceWhat outcome occurs when transmitting radio wave through Faraday cage with overly large apertures?
A)Diffraction causes signal leakage✓
B)Resonance amplifies internal fields
C)Absorption heats cage material
D)Reflection redirects wave energy
💡 Explanation
When a radio wave encounters apertures larger than a fraction of its wavelength, diffraction occurs because the EM wave bends and propagates through the opening rather than being fully blocked, causing signal leakage. Therefore signal leakage through diffraction results, rather than internal amplification, absorption heating, or simple reflection, which require different aperture constraints.
