← ScienceWhich outcome occurs when radio wave reflections combine?
A)Signal strength fluctuates spatially✓
B)Frequency band remains unaffected generally
C)Wave polarization becomes circularly aligned
D)Wavelength will increase substantially
💡 Explanation
The overlapping of waves is governed by wave interference, because the reflected waves superimpose, causing constructive and destructive interference. This spatial variation in signal strength explains fading, therefore the outcome is signal fluctuation, rather than frequency changes, which is tied to the carrier frequency.
