The back-surface reflection. - ANS 1. The indication on the instrument display that represents
the far boundary of material being tested is called:
angulation. - ANS 2. In immersion testing, the position of the transducer is often varied by a
manipulator to transmit sound into the test part at various angles to the front surface. Such a
procedure is referred to as:
coaxial cable - ANS 3. The technical name for the cable that connects the ultrasonic
instrument to the transducer is:
calibration. - ANS 4. The process of standardizing an instrument or device by using a
reference standard is called:
longitudinal wave. - ANS 5. Another name for a compressional wave is:
surface waves. - ANS 6. Another name for rayleigh waves is :

, a couplant. - ANS 7. A material used between the face of a transducer and the test surface to
permit or improve the transmission of ultrasonic vibrations from the transducer to the material
being tested is called:
crystal. - ANS 8. The piezoelectric material in a transducer that vibrates to produce ultrasonic
waves is called a
straight beam testing. - ANS 9. Ultrasonic testing of material where the probe is in direct
contact with the material being tested may be:
is one of the most efficient receivers of ultrasonic energy - ANS 10. An advantage of using
lithium sulfate in transducers is that it:
25 MHz transducer - ANS 12. The transducer that contains the thinnest piezoelectric crystal
is a:
1 MHz - ANS 13. Penetration of ultrasonic waves in a material is normally the function of test
frequency used. The greatest depth of penetration is provided by a frequency of
frequency and crystal size. - ANS 14. The amount of beam divergence from a crystal is
primarily dependent on the
refraction. - ANS 15. When an ultrasonic beam passes through the interface between two
dissimilar materials at an angle, a new angle of sound travel takes place in the second material
due to:
two times - ANS 21. The velocity of longitudinal waves is approximately __________ the
velocity of shear waves in the same material.
