Question

A microwave oven operates at 2.40 ghz. what is the wavelength of the radiation produced by this appliance? express the wavelength numerically in nanometers.

Answer 1

`\lambda = (c)/(\\u) = (3 \cdot 10^8)/(2.4 \cdot 10^9) = (1)/(8) = 0.125 \ m = 1.25 \cdot 10^8 \ nm.`

Answer 2

Answer, wavelength is
`1.25 * 10^8` nm.

The frequency of the microwave is, f = 2.40 GHz.

To Find frequency use the formula:

`c=f`λ

Where, c is the speed of electromagnetic wave or light.

f is the frequency, and λ is the wavelength of light.

Rearranging,

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

Plug in the values,
