how is light absorbed?

It is absorbed as heat.

The colored piece of glass will absorb more light which will heat it up quicker.\n\nLight goes right through clear glass. Very little light/energy is absorbed.

Each chemical absorbs a different portion of the light band. The portions that are not absorbed are what give things color. If you're looking at the spectral analysis of a star, you can tell what chemicals are present by the black bands on the light spectrum, which represent absorbed light. If that color is absorbed, then the corresponding chemical must be present.

Light only travels until it is absorbed, dissipated to other types of radiation (no longer referred to as "light"), or expended as some other form of energy.\n\nThis can mean "forever". Of course, that depends on various important factors of light which rely on concrete proof. At the moment, there are differing theories about how light works, why, and what it is.

concentration of the chromophore and wavelength of light that it absorbs. the different wavelengths give the solution (chromophore) different colours.

When you light a block of glass, part of the light will be absorbed by the glass.\nIn other words, part of the photons will be absorbed by the glass.\nOther photons will be reflected back by the block of glass, and others will pass through it.\nThe lose of energy of your light ray will be seen as a reduction in the number of photons in the ray, in other words, in a reduction in the ray's INTENSITY. Not as a change in the light's frequency.\n\nHowever, the glass will absorb certain light frequencies better than other. (Each matter has its own "absorption graph").\nBecause of that, if your light ray is not a monochromatic one, it is possible that the ratio between the different light frequencies in the ray will change.

I do not know how deep you want to go. This could get quite complicated. \n\nThe simple answer is that it absorbs infrared radiation. That is, it is opague to IR light (heat). \n\n\nHere is how it does it:\n\nLight at all wavelengths falls on the atmosphere. Some gets transmitted to the ground. The surface absorbs this radiation, and some of it gets reradiated as heat, or IR light. The carbon dioxide in the air will not let it escape out into space.\n\nOf course, one can make this far more sophisticated and detailed.\n\n- - - - - - - -  - - - - \n\nObviously this is a multiple-choice homework problem. I am afraid if you cannot figure out which answer to choose from my response, then you have some problems. You need to ask the teacher for help. I will not spoon-feed you.

If it reflects all the light, it appears white. If it absorbs all the light, it appears black.

light, for example is electromagnetic. The absorbance term for light, although dimensionless is defined as -log(T) where T is the % transmittance through the sample.

The sea is mostly salt water with suspended organisms and minerals.\n\nUnless the organisms carry a lot of pigments, there will be no specific absorption of colour. Instead, you will have unspecific absorption by particles. In this case, light on the red (low wavelength) side of the spectrum will be absorbed more than light on the blue side.\n\nYou can check this at home: pour a little milk into a glass of water so that it still remains mostly transparent and hold it against a conventional lightbulb. The glass content will appear slightly blueish.\n\nThe amount of absorption is dependent on the thickness of the layer. The more impure water there is, the bluer/blacker it will appear.

If you want to look at it on the atomic level,\nyou can think of light as a photon (a packet of energy).\nThe photons can be absorbed by the electrons around the atom which will excite them into a higher energy state.  When the electron falls back down to the ground state, it gives off a photon with a specific amount of energy.\n\nhttp://www.amazingrust.com/New/beta/Experiments/background_knowledge/Spectroscopy.html

The energy from the light is absorbed into the walls, etc.  If you could create a room that had everything in it 100% reflective, then the light would continue to exist.  But, you wouldn't know this, because you are not 100% reflective, and you would absorb the light.

Each material absorbs different wavelengths of light. It turns out that glass an air absorb very little in the visual range of the spectrum (although they absorb in other regions). However, they do absorb some. If you had a piece of ordinary glass that was very thick, it wouldn't pass much light. In fact, one reason that mountains in a distance look blue is that the longer wavelengths are absorbed by the air. On the other hand, it is possible to have pices of metal that are so thin that they pass light.

When light falls onto an object a part of the spectrum is reflected and another part is absorbed. Depending on the (micro)texture of the object, different parts of the spectrum are reflected and we sense another color. Since there is a differennce in microtexture between wet and dry clothes, we experience a slightly different color.

it gets absorbed by your surroundings.

light travels as fast as it always travels, no matter what it shines through. Things block light, but it doesn't slow it down.

Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors. The colors in white light are red, orange, yellow, green, blue and violet. You can see these colors when you look at a rainbow in the sky. \n\nThe sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust. \n\nAs sunlight goes through the air, it bumps into the molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky. \n\nWhen you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light from everywhere overhead, the sky looks blue. \n\nIn space, there is no air. Because there is nothing for the light to bounce off, it just goes straight. None of the light gets scattered, and the "sky" looks dark and black.
