What absorbs the radiation of certain wavelengths when electromagnetic radiation are passed through it?

the atmosphere
A lot of the electromagnetic radiation is absorbed by the atmosphere, with the exceptions of radio waves, microwaves, and visible light. While infrared and ultraviolet radiation are mostly absorbed by the atmosphere, they are also capable of penetrating the atmosphere at some wavelengths.

What affects absorption of electromagnetic radiation?

Although the absorption of waves does not usually depend on their intensity (linear absorption), in certain conditions (optics) the medium’s transparency changes by a factor that varies as a function of wave intensity, and saturable absorption (or nonlinear absorption) occurs.

What are the two things that may happen when radiation is absorbed by matter?

In general, two things can happen when radiation is absorbed by matter: excitation or ionization. Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.

Is electromagnetic radiation absorbed?

Electromagnetic radiation can be absorbed by any particle that carries electric charge. The absorption of electromagnetic radiation helps determine the visible appearance of objects.

Does electromagnetic radiation change wavelength?

Note speed is the same for all electromagnetic waves and as frequency increases the wavelength decreases. As you can see radio waves have the longest wavelengths and gamma-rays have the shortest.

How electromagnetic radiation affects matter when it is absorbed by matter?

The different parts of the electromagnetic spectrum have very different effects upon interaction with matter. If electromagnetic energy is absorbed, but cannot eject electrons from the atoms of the material, then it is classified as non-ionizing radiation, and will typically just heat the material.

Which electromagnetic wave can pass through metals?

The EM waves with longitudinal E component penetrate through the metal. In one experiment (http://arxiv.org/abs/physics/0010036), the authors used the metallic shield to be sure that they detected the longitudinal E field.

Which electromagnetic wave carries more energy than others?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
