When EM waves pass through things like rain and hail, they can be "obstructed" and bounced back or absorbed, rather than passing through.
I'm conducting an experiment on this effect, and wondered if there is a more scientific/nerdy way of saying this? I thing obstruction sounds somewhat unprofessional.
Looking in a thesaurus I see interference. I like that better, but it seems very vague. Is there a word that just means absorption or scattering, such that the detector can't detect them?
