Assume the velocity of sound in human tissue is v = 1540m/s and frequency f = 18MHz. We know that
Step-by-step explanation
Assume the velocity of sound in human tissue is v = 1540m/s and frequency f = 18MHz. We know that
v = f λ
λ = v/f = 1540/ (18*106)
λ = 85.55*10??m
λ = 86 μm would be the smallest feature observable in human tissue
