Question

The frequency of a microwave is 6Ghz. Calculate the wavelength of the wave in the air.

Answer 1

Answer:

$\lambda=0.05\ m$

Explanation:

Given that,

The frequency of a microwave is 6Ghz.

We know that, $1\ GHz=10^9\ Hz$

We need to find the wavelength of the wave in the air.

The relation between wavelength, frequency and speed is given by :

$c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{6\times 10^9}\\\\\lambda=0.05\ m$

So, the wavelength of the wave in the air is 0.05 m.
