Answer:
[tex]\lambda=0.05\ m[/tex]
Explanation:
Given that,
The frequency of a microwave is 6Ghz.
We know that, [tex]1\ GHz=10^9\ Hz[/tex]
We need to find the wavelength of the wave in the air.
The relation between wavelength, frequency and speed is given by :
[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{6\times 10^9}\\\\\lambda=0.05\ m[/tex]
So, the wavelength of the wave in the air is 0.05 m.
