what are applications of ultra sonic waves in various situation?
Answers
Answer: Ultrasonic waves are used around the world, indoors and outdoors in the harshest conditions, for a variety of applications. Our ultrasonic waves, made with piezoelectric crystals, use high frequency sound waves to resonate a desired frequency and convert electric energy into acoustic energy, and vice versa.
Application of Ultrasonic's wave:
1.Ultrasonic's are used in directional signaling.
2.Ultrasonic's are used in the detection of aircraft, submarines and schools of fish etc.
Ultrasonic's generated by a piezoelectric crystal generator are transmitted towards a target. These waves are reflected by an aircraft or submarine coming across their path. The reflected beam is detected by means of a quartz detector. The device used for the purpose is called SONAR – sound navigation and ranging.
3.The reflection of ultrasonic is used to estimate the depth of the sea. By measuring the elapsed time between the transmission and reception, after reflection from the bottom, of ultrasonic waves, the depth of the sea can be computed. The instrument used for the purpose is called a Fathometer
4.Heat is produced when an intense beam of ultrasonic's passes through a substance. Joints of thermoplastic materials can be welded homogeneously and water can be boiled with the heat thus generated.
5.An ultrasonic drill is used for preparing teeth for filling. Ultrasonic cleaning machines have been developed to clean very small objects such as hypodermic needles, minute parts of watches etc.
