By definition, a transparent substance has no color. It is often described as "clear."
Optical Density. Which often is caused by normal density.
It can be. Here's the problem: "rubber" is a generic terms that includes a variety of different products. There are:acrylic rubberbutadine rubberbutyl rubberchlorobutylchlorinated polyethylenechlorosulphonated polyethyleneepiclorhydrinethylene acrylicethylene propylene rubberfluoroelastomersfluorosilicone rubberhydrogenated nitrile rubberisoprene rubbernatural rubbernitrile rubberperfluoro elastomerspolycloroprenepolynorbornene rubberpolysulfide rubberpolyurethane rubberpolyethane rubbersilicone rubbersytrene butadiene rubbertetra-fluoroethylene/propyleneThere are as well more than thirty different proprietary formulas for different types of rubber. Many of these can be blended in such a wasy as to render them transparent. Have you ever seen clear in-line skate wheels? These are a form of transparent rubber, often polyurethane.
The word is refraction. It is better to say that light changes direction even though the term "bend" is often used. The phenomena is intrinsic to waves that pass through the boundary between to mediums, e.g. water waves exhibit refraction when moving from an area of deeper water to shallower water. The concept of refraction is clear and simple only when the boundary between the two mediums of the wave is flat. When an interface is not flat, the refraction, reflection and transmission concepts need a more sophisticated characterization. It should be observed that the refraction of waves at an interface is accompanied by a change in velocity of the waves as well. This is most commonly discussed for light where the speed of light in a medium is equal to the speed of light in a vacuum divided by the index of refraction of the medium. (This can be generalized to other types of waves.) Regarding wave speed and wave refraction, one can not say that one causes the other. They must happen together for everything to be consistent.
When light hits a surface it experiences reflection and refraction.Reflection occurs when the incident light bounces back off of the surface. This is the predominant response for highly reflective materials such as silver. Refraction occurs when the incident light travels through the surface. This is the predominant response with transparent materials such as glass. In every material, some light is reflected and some is refracted. However, one or the other is often negligable.

Candirus are often light blue or even transparent.
Shadows are caused by something BLOCKING the light. You can have shadows in space, if something is blocking the light. On Earth, shadows often look fuzzy; this is caused by the Sun's light being scattered in the air. In space, there is nothing to scatter the light, so shadows are sharp-edged and clear.
Optical Density. Which often is caused by normal density.
It's a lantern.
The simile "as clear as glass" means something is easily understood or transparent, just like how clear glass allows you to see through it without obstruction. It is often used to describe a situation or concept that is easy to grasp or perceive.
Candidates often talk about government being transparent. Clear water in a glass is transparent.

Anything halfway between clear (transparent) and Opaque (doesn't transmit light). I often think if a clear/white translucent like some PEX tubing, polyethylene, Teflon tubing, some tupperware, & etc. Someone suggested wax paper. Frosted Glass. Perhaps agates.
Not entirely true. It does not have to be a polished sample. It is often a transparent or semitransparent sample and the source of illumination can be a colored light or polarized light to bring out the features that need to be examined.
'Fablon'.
Glass is transparent meaning light passes through it and therefore you can see through it, but some light reflects back and if the surface is very smooth as glass often is then the light reflected back can be seen as a reflected image.
