The relationship between the speed of sound, its frequency, and wavelength is the same as for all waves: v = fλ, v = f λ, 14.1. where v is the speed of sound (in units of m/s), f is its frequency (in units of hertz), and λ λ is its wavelength (in units of meters). Recall that wavelength is defined as the distance between adjacent identical ...
اقرأ أكثرExtracorporeal shock wave lithotripsy is a technique for treating stones in the kidney and ureter that does not require surgery. Instead, high energy shock waves are passed through the body and used to break stones into pieces as small as grains of sand. Because of their small size, these pieces can pass from the body along with the urine.
