Question: The speed of sound in human tissue is on the

The speed of sound in human tissue is on the order of 1500 m/s. A3.50-MHz probe is used for an ultrasonic procedure.
(a) If the effective physical depth of the ultra-sound is 250 wavelengths, what is the physical depth in meters?
(b) What is the time lapse for the ultrasound to make a round trip if reflected from an object at the effective depth?
(c) The smallest detail capable of being detected is on the order of one wavelength of the ultra-sound. What would this be?
