Answer:
0.0000714583 m
0.0003125 m
Explanation:
v = Speed of sound in the medium
f = Frequency = 4.8 MHz
Wavelength is given by
[tex]\lambda=\dfrac{v}{f}\\\Rightarrow \lambda=\dfrac{343}{4.8\times 10^6}\\\Rightarrow \lambda=0.0000714583\ m[/tex]
Wavelength of the sound in air is 0.0000714583 m
[tex]\lambda=\dfrac{v}{f}\\\Rightarrow \lambda=\dfrac{1500}{4.8\times 10^6}\\\Rightarrow \lambda=0.0003125\ m[/tex]
Wavelength of the sound in the tissue is 0.0003125 m
