What happens to an e/m wave below that cuttoff frequency?
The energy must go somewhere.
And the moderator noted:

Although the fog mainly scatters the light it cannot absorb it without
re-radiating at some other frequency. What I would like to know is the
equivalent thing for low frequency e/m waves between the galaxies? There
must be a resulting distribution of frequencies that the low frequencies
get converted to surely?
