To determine the wavelength and velocity of ultrasonic wave through ultrasonic interferometer.
Que : 01 WHAT ARE ULTRASONIC?
Ans : The term ultrasonic is said to be the vibrations of frequencies which is greater than the upper limit of the audible range for humans that is greater than about 20 kilohertz. The term sonic is said to be applied to waves that are ultrasound of very high amplitudes. The hypersound which is sometimes known as praetor sound or the microsound is the waves of sound of frequencies that is greater than 1013 hertz.
Que : 02 WHAT IS PIEZO-ELECTRIC EFFECT?
Ans : Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and piezo, which is Greek for “push”.
Que : 03 WHAT IS INVERSE PIEZO ELECTRIC EFFECT?
Ans : The inverse piezoelectric effect converts electrical energy to mechanical energy. Using the inverse piezoelectric effect can help develop devices that generate and produce acoustic sound waves. Examples of piezoelectric acoustic devices are speakers (commonly found in handheld devices) or buzzers.
Que : 04 WHAT IS THE PURPOSE OF ULTRASONIC?
Que : 05 WHAT IS THE FULL NAME OF SONAR?
Ans : SONAR: Sound Navigation and Ranging
