Ila dear,
Please shed your majestic gaze on the above picture.
You will see, to your amazement, that Radio waves begin at
30 hertz only in the
Extremely Low Frequency Range.
ELF.
After that comes
Ultra Low Freq beginning at
300 Hz.
ULF.
After that comes
Very Low Freq, starting at
3000 Hz. Its called
VLF.
Refesh your info from time to time. Its very helpful.
Lots of love,
