(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How many wavelengths of radiation emitted by a 60 Hz electrical transmission line would it take to span the North American continent (a distance approximation 5.0*10^3 km).

f=60Hz

d=5.0*0^3 km=5.0*10^6 m

2. Relevant equations

v=fλ

Δd=vΔt

3. The attempt at a solution

Δt=d/v

= 1.67*10^-2

If speed is c then wavelength should equal c/f=3.0*10^8/60

=5.0*10^6

Which is absoloutely wrong since answer is 1.0.

Please help me and thanks in advance.
