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`.

Text Solution

Verified by Experts

`lambda=? upsilon=1.7kms^(-1)=1700ms^(-1), v=4.2MHz=4.2xx10^(6)Hz`
`lambda=(upsilon)/(v)=(1700)/(4.2xx10^(6))m=0.405xx10^(-3)m =0.405mm`
