# Solve this : 8. (a) How are the wavelength and frequency of a sound wave related to its speed?  b) A laboratory uses an ultrasonic scanner to trace tumour in tissue. The operation scanner is 4.2*106 Hz. Calculate the wavelength of sound in the tissue if the speed of the sound is 1700 m/s.

Dear Student,

(a). The wavelength and frequency of a sound wave are related to its velocity (v),
$V=\nu \lambda$
(b). Here given  and .
So, we have to find out the wavelength,

Regards
