alleryMicrowaves are suitable for radar systems in aircraft navigation because of their:
ASharp wavefronts
BSteady waveforms
CStrong watermarks
DShort wavelengths
Answer & Solution
Correct answer: D. Short wavelengths
1. Radar has to resolve objects at a distance.
2. Resolution improves as the wavelength gets shorter.
3. Due to their short wavelengths, they are suitable for radar systems used in aircraft navigation.
4. So the answer is their short wavelengths.
