ULTRASONICS
Production of ultrasonics by magnetostriction and piezoelectric methods – acoustic grating -Non Destructive Testing – pulse echo system through transmission and reflection modes – A,B and C – scan displays, Medical applications – Sonogram
INTRODUCTION
- • The word ultrasonic combines the Latin roots ultra, meaning ‘beyond’ and sonic, or sound.
- • The sound waves having frequencies above the audible range i.e. above 20000Hz are called ultrasonic waves.
- • Generally these waves are called as high frequency waves.
- • The broad sectors of society that regularly apply ultrasonic technology are the medical community, industry and the military.
PROPERTIES
- x They have high energy content.
- x Just like ordinary sound waves, ultrasonic waves get reflected, refracted and absorbed.
- x They can be transmitted over large distances with no appreciable loss of energy.
- x If an arrangement is made to form stationary waves of ultrasonics in a liquid, it serves as a diffraction grating. It is called an acoustic grating.
- x They produce intense heating effect when passed through a substance.
PRODUCTION OF ULTRASONIC WAVE
Ultrasonic waves are produced by the following methods.
- (1) Magneto-striction generator or oscillator
- (2) Piezo-electric generator or oscillator
