1(a) What frequency ultrasound should be used to see details as small as 1.0 mm in tissue? The speed of sound in tissue is 1540 m/s. Is this a maximum er minimum frequency (b) Given that the maximum effective depth is approximately 400 wavelengths, to what depth is this sound effective as a diagnostic probe? 5.0-MHz ultrasound is used to look for objects in the eve, such as fragments of glass. (c) What is the smallest detail detectable with this fiequency sound, given the speed of ultrasound in tissue is 1540 m/s? (d) is the effective depth of penetration great enough to probe the entire eve? (About 3.0 em is needed.)​
