Ultrasound probes can resolve structural details with sizes

Question

Ultrasound probes can resolve structural details with sizes approximately equal to the wavelength of the ultrasound waves themselves. What is the size of the smallest feature observable in human tissue when examined with 11-MHz ultrasound? The speed of sound in human tissue is 1,540 m/s

Answer 1

Notes: You may be using different variables, so the equation might look different.

v = velocity

f = frequency

λ is the wavelength.
