With a seismograph.
While professional seismographs use electronic transducers to detect small movements of a mass, a very simple one can be built with a simple pendulum having a pen attached to it to draw its movements on a sheet of paper.

Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
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.
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.
What are the properties of ultrasonic waves?
THE ULTRASONIC WAVES have constant velocity in homogeneous medium. Many modes of vibration. High resolution,used for flaw detection Sonic beam and highly energetic. reflection and refraction in interface.so elastic
Does an MRI create images by combining high-frequency ultrasonic waves and strong magnets?
Yes
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.
How can you trace ultrasonic waves?
What?! Trace ultrasonic waves? Are you one hundred per cent cuckoo?! Why would anyone trace ultrasonic waves these days??
Why ultrasonic waves are not electromagnetic waves?
No. They are mechanical waves, ultrasonic waves are sound waves and require a medium for propagation. The word ultrasonic denotes that they have a frequency above the audible range (above 20 KHz).
Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
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.
Can ultrasonic wave pass through 1Cm thick iron plate?
Yes. Ultrasonic waves can pass through metal. The only difference between "normal" sound waves and ultrasonic waves is that we cannot hear ultrasonic waves. However, they behave the same.
Which waves are used in sonography?
ultrasonic waves
What is ultrasonic cleaning?
Ultrasonic cleaning is cleaning through ultrasonic waves with some chemicals.
What is an ultrasonic wave?
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
How does frequency of the ultrasonic waves of the echo from the stationary object compare with frequency of the ultrasonic waves of the probe?
the frequencies are same.
Explain how ultrasonic waves can be produced in the laboratory?
using ultrasonic interferometer
Can you see ultrasonic sound waves?
Sound waves- ultrasonic, sonic, or intrasonic are generally invisible. You cannot see sound.
