Beside this, what are ultrasonic and supersonic waves?

Ultrasonic is a reference to the frequency of sound waves beyond (above) the human hearing range. Typically that's used when describing a medical imaging device. Supersonic is an adjective that describes the speed of something moving faster than sound.

Likewise, what causes a shock wave? Shock waves are formed when a pressure front moves at supersonic speeds and pushes on the surrounding air. Shock waves are not conventional sound waves; a shock wave takes the form of a very sharp change in the gas properties. Shock waves in air are heard as a loud "crack" or "snap" noise.

Correspondingly, what is the frequency of supersonic waves?

Ultrasonic and supersonic - definition Ultrasonic is used for ultrasound waves and is defined as waves with frequency more than 20 kHz. They cannot be heard by human beings. Supersonic is used for objects which travel at a speed greater than the speed of sound.

Can civilians fly supersonic?

- Quora. Yes, if you have the money. For the low, low sum of $250,000USD, you too can experience the thrill of supersonic* flight in your very own Mig-21UM. For just $4,650,000USD, you can have a jet reach 2.25 mach (2.25 times the speed of sound) at just under 60,000ft.
