Question

If a microwave oven produces electromagnetic waves with a frequency of 2.30 ghz, what is their wavelength?

Answer 1

`\lambda = (c)/(\\u) = (3 \cdot 10^8)/(2.3 \cdot 10^9) = (3)/(23) \approx 0.130435 \approx 0.13 \ m.`

Answer 2

Answer: wavelength is
`<strong> 1.30 * 10^8 nm.</strong>`

The frequency of the microwave is, f = 2.30 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,

`\lambdam = (3 * 10^8 m/s)/(2.30 GHz(10^9 Hz)/(1 GHz))=0.130 m(10^9 nm)/(1 m) = 1.30 * 10^8 nm.`
