Answer to Question #113100 in Electricity and Magnetism for Riley Flournoy

Question

If a weather station uses electromagnetic waves with a frequency of 2.85 x 10^9 Hz, what is the length of the wave

Answer 1

As $c=\nu\lambda$

So, $\lambda=\frac{c}{\nu}=\frac{3\times10^8}{2.85\times10^9}=0.1052m$
