Question

A frequency ultrasound is used to image details of abut 1 mm. If this was the smallest detectable wavelength and this sound travelled at a speed of 1500 m/sec, what is the minimum frequency of this sound wave? Write the frequency in MHz.

Explanation / Answer

v = f*lambda

v = 1500 m/s

lambda = 1*10-3 m

f = v/lambda = 1500 / 1*10-3

minimum frequency of this sound wave is, f = 1.5 MHz
