Explanation:
A hospital uses an ultrasonic scanner to locate tumour in a tissue. What is the wavelength of sound in a tissue in which the speed of sound is 1.7 km//s ? The operating frequency of the scanner is 4.2 MHz .
Speed of sound in the tissue, v = 1.7 km/s
m/s <br> Operating frequency of the scanner, ν = 4.2 MHz
Hz <br> The wavelength of sound in the tissue is given as: <br>
