Question

A microwave oven operates at 2.50 GHzGHz . What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers.

Answer 1

Answer:

The wavelength is $\lambda = 1.2 * 10^8 nm$

Explanation:

From the question we are told that

   The frequency of operation of the microwave is  $f = 2.50 GHz = 2.50 *10^{9} \ Hz$

     Generally the wavelength is mathematically represented as

          $\lambda = \frac{c}{f}$

Here c is the speed of light with value $c = 3.0 *10^{8} \ m/s$

So  

         $\lambda = \frac{3.0 *10^{8}}{ 2.50 *10^{9}}$

=>       $\lambda = 0.12 \ m$

converting to nanometer

           $\lambda = 1.2 * 10^8 nm$
