Harmonics are often seen on shaft and blade signatures of surface ships and become broad and diffused with cavitation. also main electrical power sources will show harmonics related to pole pairs on the motors etc.
amplitude at resonance is large[maximum] but finite
What is meant by resonance and explain the series and parallel resonance? by kathiresan
Sonar, Lidar.
Series resonance is called voltage resonance because at resonance frequency in a series RLC circuit, the impedance of the inductor and capacitor cancel each other out, resulting in minimum impedance. This causes the total voltage across the circuit to be maximized, leading to a peak in voltage across the components at resonance. This phenomenon is known as voltage resonance because it results in a maximum voltage across the circuit at that specific frequency.
The freqeuncy (or pitch) of the sonar is not generally the factor which is likely to effect wildlife, but the amplitude (how loud it is).

Sonar.
A submarine uses sonar, like a bat uses echolocation to see.
They use SONAR
bats and dolphins
Some animals like bats and dolphins use sonar to see by emitting sound waves that bounce off objects and return to them, allowing them to "see" their surroundings. Submarines and ships also use sonar technology for navigation and detecting underwater objects.
Sonar is used to gain information about objects underwater which you can't see because of the darkness and/or opacity of the water.
