← ScienceWhich outcome arises when pulsed radar operates near buildings?
A)Constructive interference creates signal nulls.✓
B)Dielectric saturation reduces absorption loss.
C)Faraday rotation alters polarization planes.
D)Raman scattering shifts the signal spectra.
💡 Explanation
Constructive interference causes areas of signal nulls when reflected waves overlap because the reflected electromagnetic waves undergo superposition. Therefore, signal strength weakens; rather than options depicting material property changes or inelastic scattering processes.
