What electromagnetic waves do not transport?

Answer 1

When photons collide with any matter, the radiation attenuates and energy is released as heat. There is variation in the ability of an electromagnetic wave to travel in a given medium, and its ability varies with the nature of the medium and the frequency of the electromagnetic wave. We know that we can see through window glass and clear acrylic plastic. But we can't see through a brick wall or a block of steel.

Answer 2

Yes, electromagnetic waves can travel through some mediums. But they cannot travel through others. When we consider optical wavelengths, we know that we can see through window glass or clear acrylic plastic or a glass of water. On the other hand, we can't see a light bulb through a sheet of steel or a brick wall. The bottom line is that the ability of electromagnetic radiation to travel through a medium depends on the nature of the medium and the frequency of the radiation.

Answer 3

Electro magnetic waves do not require a medium to travel. Some scientists believe, however, that all "empty space" is filled with a mass-less medium called ether. This is just a hypothesis however and remains unproven.

Answer 4

Electromagnetic radiation moves most rapidly through vacuum. No medium--just empty space. Light also propagates through air, water, clear glass. Radio signals, which are long wave light, can penetrate through inches of concrete. This is why your radio appears to fade out beneath underpasses and in tunnels or deep canyons.

Neutrinos, a highly energetic form of electromagnetic radiation, may penetrate through entire stars or planets unfazed.

Opaque solids: lumps of rock, steel, wood, dry-wall, etc.
