Vedclass · Answer

(A) Given: Frequency $(v)$ = $4.2 	imes 10^{6} 	ext{ Hz}$,Speed of sound $(V)$ = $1700 	ext{ m s}^{-1}$.We know the relationship between speed,frequency,and wavelength is given by the formula: $V = v \lambda$.To find the wavelength $(\lambda)$,we rearrange the formula: $\lambda = V / v$.Substituting the given values: $\lambda = 1700 / (4.2 	imes 10^{6})$.$\lambda = 404.76 	imes 10^{-6} 	ext{ m} \approx 4.04 	imes 10^{-4} 	ext{ m}$.

$A$ laboratory uses an ultrasonic scanner to trace a tumour in tissue. The operating frequency of the scanner is $4.2 \times 10^{6} \text{ Hz}$. Calculate the wavelength of sound in the tissue if the speed of the sound is $1700 \text{ m s}^{-1}$.
