Answer: [tex]8.52(10)^{10} Hz[/tex]
Explanation:
The frequency [tex]\nu[/tex] of a wave is given by the following equation:
[tex]\nu=\frac{c}{\lambda}[/tex]
Where:
[tex]c=3(10)^{8} m/s[/tex] is the speed of light
[tex]\lambda=3.52 mm=3.52(10)^{-3} m[/tex] is the wavelength of a microwave
Hence:
[tex]\nu=\frac{3(10)^{8} m/s}{3.52(10)^{-3} m}[/tex]
[tex]\nu=8.52(10)^{10} s^{-1}=8.52(10)^{10} Hz[/tex]
