With special electronically driven crystals, it is possible to produce mechanical waves at any frequency up to a few million Hertz (cycles per second). If the sound waves are above 20kHz (the maximum humanly audible frequency) they are called ultrasonic waves. Because of their short wavelength, ultrasonic waves can be focused onto small areas and can be imaged much as visible light. Ultrasonic waves penetrate tissue and are scattered and absorbed within it. Using specialized techniques called ultrasound imaging, it is possible to form visible images of ultrasonic reflections and absorptions. Therefore, structures within living organisms can be examined with ultrasound, as with X-rays. Ultrasonic examinations are safer than X-rays and often can provide as much information. In some cases, such as in the examination of a fetus and the heart, ultrasonic methods can show motion, which is very useful in such displays.
Here are a few:
Ultrasonic cleaning
Ultrasonic motion detection
Ultrasonic welding
Ultrasonic sonography
Ultrasonic communication
Ultrasonic destruction
Heart exams
Pre-natal investigation
What else can I help you with?
Can you see ultrasonic sound waves?
Sound waves- ultrasonic, sonic, or intrasonic are generally invisible. You cannot see sound.
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.
What is a heart exam that uses sound waves?
EchocardiogramUltrasound?
What is a sentence using the word ultrasonic?
My toothbrush uses ultrasonic vibrations to help clean my teeth and gums.The sound of an ultrasonic dog whistle can be heard by dogs, but not by humans.
Bats can sense obstacles because they produce 1. supersonic sound waves 2. ultrasonic sound waves 3.infrasonic sound waves 4. micro Sound waves?
Bats produce ultrasonic sound waves to sense obstacles in their environment. These waves bounce back, allowing bats to navigate and locate objects in the dark.
Which sound waves can be called ultrasonic?
Ultrasonic means 'faster than sound'. This means no sound wave can be faster than sound.
High frequency sound waves are know as?
Ultrasonic sound.
What is the speed of ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?
No, ultrasonic wave do not travel at all in a vacuum.
Are ultrasonic waves called as electromagnetic wave?
No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.
What part of the electromagnetic spectrum does the ultrasonic wave falls into?
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
Bats can sense obstacles because they produce which waves?
ultrasonic sound waves
What is the wavelength of ultrasonic sound?
The wavelength of ultrasonic sound typically ranges from 1 mm to 1 cm, corresponding to frequencies higher than the upper limit of human hearing (20 kHz). Ultrasonic sound waves have shorter wavelengths compared to audible sound waves.
