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

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

Step-by-step 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  =  (c)/(f)`

Here c is the speed of light with value
`c =  3.0 *10^(8) \  m/s`

So

`\lambda  =  (3.0 *10^(8))/(  2.50 *10^(9))`

=>
`\lambda  =  0.12 \  m`

converting to nanometer

`\lambda  =  1.2  * 10^8 nm`
