It also is used to monitor how properly medications are working. Valves in the coronary heart maintain blood flowing in a single path when the guts pumps.
W. Pierce of the USA constructed an instrument, the Pierce interferometer, for measuring with excessive accuracy the rate and absorption of ultrasonic waves in gases and liquids. Several important contributions have been made by the American physicist R.
An necessary contribution was made by the French physicist P. Langevin, who in 1916 turned the first to make use of the piezoelectric properties of quartz for the technology and reception of ultrasonic waves within the detection of submarines and the measurement of sea depths.
Sokolov initiated ultrasonic flaw detection for metal products by proposing the use of ultrasound to detect cracks, cavities, and different defects in solids. A particularly quickly creating department of flaw detection is that involved with acoustic emission.
