When a reflector is 2cm deep, a pulses time-of-flight is _____.

Time-of-flight is the round-trip travel time of the ultrasound pulse, determined by how far it must go and the speed of sound in the medium. In soft tissue, the speed of sound is about 1540 m/s. A reflector 2 cm deep is 0.02 m away on the way down, so the pulse travels a total of 0.04 m round trip. Time = distance / speed = 0.04 m / 1540 m/s ≈ 2.6 × 10^-5 s, which is about 26 microseconds.
