Answer: [tex]5.79\times 10^{7}\ \text{Hz}[/tex]
Step-by-step explanation:
Given
Speed of radar wave [tex]v=2\times10^{6}\ m/s[/tex]
the wavelength of radar wave [tex]\lambda =0.0345\ m[/tex]
We know, [tex]velocity=frequency\times wavelength[/tex]
[tex]frequency=\dfrac{\text{velocity}}{\text{wavelength}}[/tex]
[tex]frequency=\dfrac{2\times10^6}{3.45\times10^{-2}}[/tex]
[tex]frequency=5.797\times 10^{7}\ Hz[/tex]
