Why loudspeaker cannot be used to produce ultrasonic waves?
What are ultrasonic and infrasonic sound waves?
Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz. Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake. Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays. Grade 11 Physics

Can ultrasonic wave pass through 1Cm thick iron plate?
What are the uses of ultrasonic sound waves?
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
Asked in The Difference Between
What is the difference between ultrasonic and infrasonic sound waves?
What is the reason for ultrasonic waves not being in the form of electromagnetic waves?
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
