UV light can only measure a bandwidth up to a certain point. The result of using a UV spectrometer when your sample is too thick could lead to inaccurate numbers due to the fact that there are too many molecules present. Using a narrower sample reduces the amount of noise and there are not as many elements giving off energy that could alter your results.

A material through which light (or a certain color of light) won't pass through is said to be OPAQUE for light (or for that color of light). Most materials around us are opaque for visible light; only a few materials, such as air and other gases, water, and glass, are transparent, meaning they do let light through.
wavelength from 0.9 to 7.0 so in a way you can say that the wavethength is short.First, a basic fact: light in the SWIR band is not visible to the human eye. The visible spectrum extends from wavelengths of 0.4 microns (blue, nearly ultraviolet to the eye) to 0.7 microns (deep red). Wavelengths longer than visible wavelengths can only be seen by dedicated sensors, such as InGaAs. But, although light in the shortwave infrared region is not visible to the eye, this light interacts with objects in a similar manner as visible wavelengths. That is, SWIR light is reflective light; it bounces off of objects much like visible light. As a result of its refelctive nature, SWIR light has shadows and contrast in its imagery. Images from an InGaAscameraare comparable to visible images in resolution and detail; however, SWIR images are not in color. This makes objects easily recognizeable and yields one of the tactical advantages of the SWIR, namely, object or individual identification.
No. Light cannot pass through glass or water. Light bulbs do not shine, and flashlights are a myth. The presence of air alone is enough to totally block the passage of heat, such as from a fireplace or heat lamp. Not only that! Radio waves cannot penetrate walls ... the reason why radios, TVs, and cellphones are completely useless inside the walls of a home. Finally, X-rays are totally blocked by the presence of tooth enamel or human skin, and microwave radiation is utterly unable to penetrate leftover meatloaf, and it bounces off harmlessly.

UV light doesn't fully penetrate it. At deepest, it only penetrates less than a millimeter and still doesn't make it past the top layer of skin.
The ocean is heated only by the sun. Light and heat do not penetrate deep in the ocean water...
Yes. A bar code scanner uses laser light. The light is of too low a power to burn skin, does not use frequencies that can penetrate skin. The only danger presented is to the eye if you stare into the light.

IF you use LIGHT response as a measure of different kinds of material, there are only THREE types Opaque = Light cannot penetrate, or bounce from the material well. Variations on this include only certain KINDS of light can penetrate it. IE UV glass that passes Optical light, forbids UV light. Translucent = Allows the majority of light to pass through. glass is the obvious example, and cloudiness or coloration is the obvious exception. Refractive = Any material that allows SOME light to pass through, but alters it's direction, often in different responses to the FREQUENCY of the light it encounters. OF COURSE, many materials exhibit all three properties to some degree
Size varies from person to person, but typically its about the size of its owners' clenched fist.

Fog is in essence tiny water particles. The light goes into a straight line as long as there are no objects colliding with it. However, water not only stops the light particles, it refracts them, causing the light to go in every direction except straight ahead.

Off white, because this is the only colour that reflects all light and absorbs no rays in visible spectrum.
Please rephrase - the question is unclear.
