False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
what waves cannot penetrate the atmosphere
radio telescopes
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
s waves
they use high frequency sound waves to penetrate deep into the atmosphere and possibly a black hole if you are lucky
I think the radio waves penetrate according to the barrier leakage or tunneling as explained by quantum mechanics.
By the earths atmosphere
