When light shines on a material, how much of the light interacts with the electrons and the nucleus?

Consider that at visual frequencies, The wavelength of light is, very roughly, three orders of magnitude larger than atoms. The energy in visible light, very roughly, one eV, is about three orders of ...

Will gamma radiation cause "thermal" decomposition of sodium bicarbonate?

I think you are looking in the wrong direction. If you subject oxoanions such as sulfate or nitrate to intense gamma ray fields then you will see decomposition of the anions to form oxygen and ...

When light shines on a material, how much of the light interacts with the electrons and the nucleus?

When light shines on a solid surface, what % of light hits the electrons and what % hits the nucleus? If we replace "hit" with "scatter from or become absorbed by" and restrict ...

When light shines on a material, how much of the light interacts with the electrons and the nucleus?

Matter is energy trapped in a field or fields that give the energy certain properties that we manage to measure or at least acknowledge. Photons seem to be pure energy, however, they have properties ...

The use of far-infrared ceramics for water purification?

Thank you for the question. Water molecules have a natural oscillation frequency of 2 micrometres. Not true. There is some absorption in infrared (≈ 1 µ- 10 µ), but this is neither dominant, nor is ...

Why is hydrogen peroxide kept in dark colored bottles?

True white reflects "all" light, but most plastic bottles that look white actually are translucent, reflecting and scattering some light, but transmitting quite a bit, too. Lining a bottle ...

When light shines on a material, how much of the light interacts with the electrons and the nucleus?

Edit: I've replaced occurrences of the word "hit(s)" with "interact(s) with" as the former term is not to the liking of those who prefer using perfect terminology. All the ...

Which gamma radiation had more high-energy?

There is no simple relationship between the half life of a radionuclide and the decay energy. Radioactivity only occurs when it is thermodynamically possible for a nuclear reaction to occur in the ...
