What measurement must the machine make so that it can calculate the distance?​

Answer 1

Answer:

Hiii dear

here is your answer ✌☺

Explanation:

Abdominal scans may use a 7-MHz frequency, and the speed of sound in tissue is about 1540 m/s—so the wavelength limit to detail would be λ=vwf=1540 m/s7×106 Hz=0.22 mm λ = v w f = 1540 m/s 7 × 10 6 Hz = 0.22 mm .
