By using Wheat's stone bridge we can detect by thermal method.
placing platinum wire in which ultrasonic waves have to be tested, due to change in temperature produced in the wire resistance of the wire changes, it is noted by using galvanometer in the bridge.

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 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.
How you can detect waves?
to detect ultrasonic waves ,place a sensitive flame in its path. if it flickers it proves its existence.
What other animal can detect ultrasonic waves?
Bats, dolphins, dogs.
Describe at least three uses of ultrasonic technology in medicine?
Medical professionals can send ultrasonic waves into a specific part of the patient's body. Reflected ultrasonic waves are used to detect and monitor conditions such as pregnancy and certain types of heart disease and cancer.
Form of sonar used to detect and locate enemy submarines by means of ultrasonic waves?
Type your answer here... ASDIC
What electromagnetic waves can thermal cameras detect?
The infrared spectum since this is attributed to heat.
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??
How do you stop ultrasonic waves?
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.
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.
