Humans can hear sound around ca. 20 - 20,000 vibrations per second; ultrasound is sound beyond that (faster).
Sound is produced by making the air vibrate - with a vibrating object.
Such sound can be produced by a transducer - specifically, one that uses a physical effect to convert electrical signals into vibrations. Producing a high-frequency electrical signal is relatively easy.
What else can I help you with?
Explain how ultrasonic waves can be produced in the laboratory?
Ultrasonic waves can be produced in the laboratory using a device called an ultrasonic transducer. The transducer converts electrical energy into mechanical vibrations, which generate the ultrasonic waves. These waves can be used for various applications, including medical imaging, cleaning, and material testing.
Can a grasshopper produce ultrasonic waves?
yes
Bats can sense obstacles because they produce which waves?
ultrasonic sound waves
The bats can fly in the dark because?
They produce ultrasonic waves.
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.
Why can't we produce ultrasonic waves by loud speakers?
Loud speakers can produce ultrasonic waves. But since the normal purpose of loud speakers is to produce sounds for people to hear, there is seldom a reason to produce sounds that people can't hear (other than to annoy certain animals).
What do bats produce that makes it possible for them to sense obstacles?
Ultrasonic sound waves
Why loudspeaker cannot be used to produce ultrasonic waves?
Loudspeakers are designed to operate within the audible frequency range (20 Hz to 20 kHz) and are not capable of producing ultrasonic frequencies (above 20 kHz) due to limitations in their design and material properties. At higher frequencies, the components of the speaker system, such as the cone and coil, are not able to efficiently reproduce the ultrasonic waves, resulting in distortion or damage to the speaker. Specialized transducers or speakers designed for ultrasonic frequencies are needed to produce sound waves in the ultrasonic range effectively.
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.
Why loudspeaker cannot be used to produce ultrasonic?
because speakers doesn't create ultrasonic waves, they create sound waves
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 is the standard value of velocity and wavelenght of ultrasonic waves in benzene?
The standard value of velocity of ultrasonic waves in benzene liquid is 1260 m/sec.
