Ultra sonic waves are a sound frequency that is oftentimes silent to humans. Research shows there is no long term negative affects due to exposure to these sounds.
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
You can use ultra sonic waves to image heart valves, to apply therapeutic heat, and the break up kidney stones, to name just three uses.
Sound waves are classified as mechanical waves because they require a medium, such as air or water, to propagate. They are longitudinal waves, meaning the particles of the medium vibrate parallel to the direction of wave propagation.
They use their pincers to snap at the air and send ultra sonic waves through the ocean
They use ultra sound waves that are bounced off the bottom of a body of water. Newer depth finders use sonic waves.
Assuming you mean a super form called Ultra Sonic, No
Correction, Yes there are such beings as Solar Sonic and Ultra Sonic, however, they does not make an Apperance in any of the games, Solar and Ultra Sonic only appeared in the Comics, Ultra Sonic was the Base form Sonic would Assume when he collected a certain Number of Rings (1000 i believe) and he could change his form based on the climate of the Area he is in, Solar Sonic assumes control when Ultra Sonic is in a hot, Arid area, such as a Desert, there is also Eco Sonic for forests and Polar Sonic for Ice caps
None ! Some animals such as bats, use ultra-sonic sound to locate prey, and 'see' in the dark.
ultrasonic waves are not used but radio waves are used in radar technology because ultra sonic waves generally create an image out of the object while we have to confine our study to the geometrical measurements only
Ultra Sonic first appears in Sonic the Hedgehog #'s 65 and 66, with additional appearances in Sonic the Hedgehog #71 and Super Sonic Special # 15.
they change colors
