Hi everyone! I was wondering why is it that radio waves can penetrate the earths atmosphere but other rays dont?
I also once watched a sci channel program in which the narrator said how certain stars "hiding " behind galactic dust ( something like that ) can be "seen" in the infrared spectrum but not in the normal visible light spectrum. my question is how are the infrared rays and their wavelengths able to break through certain stuff while visible light is stopped from passing through the dust? is there a relationship between wavelength and the density/ makeup of things they are trying to penetrate?
