Microwaves move at the speed of light which is equal to 3 x 10^8 m/s. The frequency of a wave is calculated by dividing its speed by the wavelength. Through that approach,
                                       f = (3x10^8 m/s)(100 cm/1m) / 3.5 cm
                                         = 8571428571/s = 8 571 MHz

  

Answer:

[tex]0.86\times 10^{10} Hz[/tex]

Explanation:

Given that, the wavelength of the microwave radiation is,

[tex]\lambda=3.5 cm=3.5\times 10^{-2}m[/tex]

And as we know that the speed of the wave is,

[tex]v=3\times 10^{8}m/s[/tex]

Now the frequency of the microwave radiation can be calculated as

[tex]f=\frac{v}{\lambda}[/tex]

Here, f is the frequency of microwave signal, v is the speed of the signal and  [tex]\lambda[/tex] is the wavelength of signal.

Now put all the given variable in above equation.

[tex]f=\frac{3\times 10^{8}m/s}{3.5\times 10^{-2}m } \\f=0.86\times 10^{10} Hz[/tex]

This the required frequency.
