But there is a reason why it sounds so confusing even to an advanced student -- even though EM radiation is at the heart of this science it is often surprisingly difficult to find correct and conclusive information on related topics.
For example, finding answers to questions like "Why does absorption of EM waves in matter rise with lower wavelengths, but at the wavelengths of light matter starts to become more and more transparent again" isn't easy. But so are the involved phenomenons, after all.
