The microwaves have a frequency of 1.8 x 10^9 Hz and travel at a speed of 3.0 x 10^8 m/s. Calculate the wavelength of the microwaves. Give your answer to two significant figures

0.17 m

Explanation:

The formula to apply in this question is that of speed of light.

The speed of the microwaves :

v = f * λ where f is frequency of the microwave, λ is the wavelength  and v is the speed of the wave

3.0 x 10⁸ = 1.8 x 10⁹ *λ

3.0 x 10⁸ / 1.8 x 10⁹ = λ

λ  = 0.16666666666

λ = 0.17 m { two significant figures}

what is the question because that is not a question.

your answer is, orbit around the nucleus
