When the wavelength of the radiation is much smaller than the distances of the lattice of solids the em radiation behaves mostly as photons going through and either hitting a nucleus (very small area) or not | |

| Mar 6, 2016 at 14:54 | comment | added | Judge | I believe there may be some confusion about the word penetrate. In the context of electromagnetic radiation, penetrating a substance means that the electromagnetic radiation has passed through the substance, i.e. not necessarily exerted a force on the substance. With regards to electromagnetic radiation interacting with matter, electrons and protons have an electric charge, so an electric wave could effect them. Similarly, electrons, protons and neutrons all have a magnetic moment which could be affected by a magnetic wave. Light is an electromagnetic wave, so it makes sense they interact. | |
