The outcome depends on the make-up of the material that the EM waves comes in contact with. It comes down to the size of the wave versus the density of the material. X-rays can pass through most solid objects because solid objects are composed of molecules. While the object looks solid to our eyes, there are really spaces between the molecules through which X-rays can pass but the light waves are too big. Lead is very dense. It's spacing is much smaller. Thus, the X-rays can not pass through.
