parallel to the rolled surface
In ultrasonic testing, a liquid coupling medium between
the crystal surface and the part surface is necessary
because: - ....ANSWER...An air interface between the
crystal surface and the part surface would almost
completely reflect the ultrasonic vibrations
,Entry surface resolution is the characteristic of an
ultrasonic testing system which defines its ability to: -
....ANSWER...Detect discontinuities located just beneath
the entry surface in the part being tested
During ultrasonic testing by the immersion method, it is
frequently necessary to angulate the transducer with a
discontinuity is located in order to: - ....ANSWER...Obtain
a maximum response if the discontinuity is not originally
oriented perpendicular to the ultrasonic beam
All other factors being equal, the mode of vibration that
has the greatest velocity is the: -
....ANSWER...Longitudinal wave
On the area amplitude ultrasonic standard test blocks, the
flat bottom holes in the blocks are: -
....ANSWER...Different in diameter, increasing by 0.4mm
(0.016in) increments from the No. "1" block to the No. "8"
block,
,In immersion testing, verification that the transducer is
normal to a flat entry surface is indicated by: -
....ANSWER...Maximum reflection from the entry surface
A piezoelectric material can: - ....ANSWER...convert an
mechanical energy to electrical energy
The shortest wavelength pulse is produced by the
frequency of: - ....ANSWER...25 MHz
The angle of incidence is: - ....ANSWER...Equal to the
angle of reflection
On many ultrasonic testing instruments, an operator
conducting an immersion test can remove that portion of
the display presentation that represents water distance by
adjusting a: - ....ANSWER...Sweep delay control
"100,000 cycles per second" can be written: -
....ANSWER...100 kHz
, A transducer with a frequency greater than 10 MHz will
most likely be used during: - ....ANSWER...An immersion
test

vibrations travel through the material is referred to as: -
....ANSWER...Attenuation
A term used to describe a numerous small indications on
the instrument display resulting from the test part
structure, numerous small discontinuities, or both is often
referred to as: - ....ANSWER...Hash
When testing a plate, increasing the frequency of an
ultrasonic longitudinal wave will result in: -
....ANSWER...No change in its velocity
