Supersonic waves are waves that can travel faster than normal sound waves.
Supersonic frequency is fast sound waves.
That's a sonic boom. Sound waves are never supersonic in themselves, objects can be supersonic ... which causes a pressure wave (which moves at "sonic" speeds) and which can be heard (firing a gun will do it).
the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
Ultrasonic waves are those, whose frequencies are above the frequency range of human ears (normally 20kHz). Whereas supersonic waves are those, which travel faster than sound, i.e. whose velocity is more than the velocity of sound waves.
ultrasonic sound waves
1. It is used for super speed flights like Concorde and other army planes. 2. it is used for making certain cars faster. 3. it is used for various body scans . 4. it is used for detecting cracks in metals.
A Hartmann generator is an electronic device that produces shock waves. It does this on the edge of a nozzle using a supersonic gas resonate.
bats can hear sounds of higher frequency than humans (supersonic) because they produce them and these sound waves echo back to them by bouncing of items so that they can see how far something is. Just like in submarines. therfore they need to 'hear' these 'supersonic' waves to see.
Industries that have longitudinal waves are cell phones, radio stations, television stations, and other industries that use sound waves.
