Hi All,
I'm reading about the attenuation of radio waves in space and I understand that, in addition to the normal attenuation that is proportional to the inverse of the square of the distance, there is also a loss due to the medium.
This surprised me as I thought that there was no loss in space due to energy absorbed by the medium. Is this loss because space is not actually a vacuum but contains a few atoms here and there and these atoms absorb energy from the radio waves?
Thank you,
Bob
