I have a to find the frequency of "30 m radio waves" that have a given velocity. My question is does the "30 m" refer to wavelength? I think it does but am wondering could it also be taken to refer to amplitude.

Answer 1

30 m is wavelenth. Radio waves have amplitudes in electromagnetic fields, E and H. The units for E is volts/meter, and H in Teslas.

Answer 2

Thanks so much!
