the velocity of longitudinal wave is determined by the ✔Correct answer-material properties
the material in a search unit which controls the search unit ringing is called ✔Correct answer-
the damping material
which of the following search units would contain the thinnest crystal ✔Correct answer-the
crystal vibrating at the highest frequency
piezoelectric crystals convert ✔Correct answer-electrical energy to mechanical energy
or mechanical energy to electrical
the number of complete waves which pass a given point in a given time period is referred to as
the ✔Correct answer-frequency
ultrasonic sound is defined as sound whose frequencies exceed ✔Correct answer-20000 Hz
what is the formula for for solving for wavelength ✔Correct answer-W=V/F

which instrument control alters the spacing between signals ✔Correct answer-range
the indication on the oscilloscope screen which represents the far boundary of the material
being tested is called ✔Correct answer-the back reflection
the piezoelectric material in a search unit or probe which vibrates to produce ultrasonic waves is
called ✔Correct answer-a crystal
the ultrasonic testing of material where the search unit is in direct contact with the material
being tested is called ✔Correct answer-straight beam contact testing
surface wave tesing
or angle beam testing
a test method employing two seperate search units(or probes) on opposite surfaces of the
material being tested is called ✔Correct answer-through-transmission testing
