Re: What is the highest-frequency sound that can exist in Earth's atmosphere?

There is a natural cutoff set by the average distance between two air
molecules, I guess. Everything with wavelengths shorter than that will
not propagate any more.

Hi:

What is the highest-frequency sound that can exist in Earth's
atmosphere?

AFAIK, there is no limit, but I would like some clarification.

Is it possible for a pure-sine-wave tone of 140 dB, 10^10,000 Hz [i.e.
10-to-the-power 10,000
Hz; or 10 followed by 10,000 zeros] to exist on Earth's atmosphere?

What determines the upper limit of high-frequency in the air?

Thanks,

Radium
