Why does glass allow light to pass through it but not wood? Which property of glass is responsible for it?

Answer 1

Ordinary glass is transparent to visible light due to an absence of electronic transition states in the range of visible light, and because ordinary glass is homogeneous on all length scales greater than about a wavelength of visible light. Ordinary glass partially blocks UVA (wavelength between 400 and 300 nm) and totally blocks UVC and UVB (wavelengths shorter than 300 nm) due to the addition of compounds such as soda ash (sodium carbonate).

Pure SiO2 glass (also called fused quartz) does not absorb UV light and is used for applications that require transparency in this region, although it is more expensive. This type of glass can be made so pure that, when made into fibre optic cables, hundreds of kilometres of glass are transparent at infrared wavelengths. Individual fibres are given an equally transparent core of SiO2/GeO2 glass, which has only slightly different optical properties . Undersea cables have sections doped with erbium, which amplify transmitted signals by laser emission from within the glass itself. Amorphous SiO2 is also used as a dielectric material in integrated circuits, due to the smooth and electrically neutral interface it forms with silicon.

Answer 2

Glass DOES allow wood to pass through, by breaking. The property of glass that allows wood to pass through is called BRITTLENESS.

Answer 3

Frequency and wave-length are 2 components of an identical oscillation. can no longer replace one without affecting the different. If gentle differences colour via a tinted glass, it potential that basically that area of the spectrum (frequencies and wave lengths) passes throughout the glass. The others are absorbed or pondered.

Answer 4

i guess because molecules in glass is not as closely binded as molecule in woods, the space between molecules allows light to pass through.

Answer 5

Visible light is not in the absorption spectrum of glass. That is why it passes thru.

Answer 6

the glass is transparent and the wood is not!

Answer 7

Its called transparancy.
