Question

Part a a microwave oven operates at 2.90 ghz . what is the wavelength of the radiation produced by this appliance? express the wavelength numerically in nanometers.

Answer 1

`\lambda = 0.103 m = 1.03 * 10^8 nm`

Step-by-step explanation:

As we know that microwave is an electromagnetic wave which travels with the speed of light

it is given as

`v = 3* 10^8 m/s`

it is given that the frequency of the microwave is

`f = 2.90 ghz`

`f = 2.90 * 10^9 Hz`

now from the formula of wavelength we will have

`\lambda = (c)/(f)`

now plug in all values in it

`\lambda = (3 * 10^8)/(2.90 * 10^9)`

`\lambda = 0.103 m`
