← ScienceWhich outcome occurs when a submarine's active sonar encounters thermocline?
A)Signal reflection diminishes overall range
B)Harmonic resonance causes hull cavitation
C)Refraction creates shadow zones nearby✓
D)Doppler shift increases detection range
💡 Explanation
Sound waves bend due to varying densities via refraction creating shadow zones behind the thermocline. Because sonar signals bend away from the warmer water, targets within a zone are thus hidden, rather than enhanced by constructive noise interference.
