103. Which one of the following frequencies wouldprobably result in the greatest ultrasonic attenuationlosses?a. 1 MHzb. 2.25 MHzc. 10 MHzd. 25 MHzB.47104. The product of the sound velocity and the density of a material is known as the:B.15-16; F.234105. The amplifier range over which the unsaturatedsignal response increases in amplitude in proportionto the discontinuity surface area is the:A.195106. What kind of waves travel at a velocity slightly lessthan shear waves and their mode of propagation isboth longitudinal and transverse with respect to thesurface?A.43-45; B.12-13107. Which ultrasonic test frequency would probably provide the best penetration in a 30 cm (12 in.) thick specimen of coarse-grained steel?a. 1 MHzb. 2.25 MHzc. 5 MHzd. 10 MHzB.47108. During immersion testing of an ASTM UltrasonicStandard Reference Block, a B-scan presentationsystem will show a:A.180-181; B.27-28109. Properties of shear or transverse waves used forultrasonic testing include:B.12; F.233110. One of the most common applications of ultrasonictests employing shear waves is for the:B.6533Review QuestionsCopyright by ASNT (all rights reserved).
