← ScienceWhich outcome occurs when a submarine's sonar array experiences thermal gradients?
A)Sound speed profile distortion occurs✓
B)Decreased transducer element capacitance results
C)Increased ferromagnetic material hysteresis arises
D)Spurious electromagnetic radiation emission happens
💡 Explanation
Sound speed varies with temperature; therefore variations cause refraction gradients altering the sonar's acoustic path, and beamforming accuracy diminishes, referred to as sound speed profile distortion because the wave propagation is affected, rather than capacitance or magnetic properties changes.
