What is opaque in science?
Opaque basically means that something is not transparent; light can not pass through. For an example: the choroid of the eye is opaque, it absorbs excessive light so multiple images do not appear on the retina. Keep in mind that absorbing light is not the same thing as passing through. The choroid basically stops too much light from hitting the retina.
How can you measure how much light is absorbed by an opaque object?
u can use a light sensor to meaasure the amount of light at first and in the end and find the difference between them.
The measure of how much a ray of light bends when it enter the material?
The measure of how much a ray of light bends when it enters the material is called the index of refraction.
Is material transparent if 97 percent of light passes through it?
Technically, transparency is not an on or off (yes or no) thing. There is a degree of transparency and one quantifies this by saying how much (and at what wavelengths) light is transmitted through a medium. Nonetheless, in daily language people say something is transparent when most of the light passes through and a transmission of far lesss than 97 percent falls into that category. Similarly, people use the term opaque when most of the light does not pass through a material but that usually means no detectable light or a very small fraction of light passes through.
Why do opaque objects appear to hve different colors?
This applies not only to opaque objects. The basic idea is that white light is a mixture of different colors, and objects tend to reflect the different colors - the components of white light - in different proportions. For example, an object that reflects most of the red light but not much of the other colors will look red.
Does black absorb the most sunlight?
Yes, black material absorb the most light. That's why you can't see much in a dark room; there isn't any light in a dark room, so everything appears black.
Is glow in the dark material fluorescent?
They are sort of related; however, glow in the dark materials are actually referred to as phosphorescent. The whole idea behind photoluminescence is that a material absorbs radiation (light) and then re-emits it. Phosphorescent materials absorb light, but release it at a much slower rate. Therefore, they absorb light when they are exposed to it, and then continue releasing it after the light source is removed. Fluorescence, on the other hand, is a material that that absorbs ultraviolet radiation (such as light from a black light) and then releases visible light.
What is meant by the solubility of material in water?
The solubility of a material in water is how much the object can absorb.
What are some ways in which materials affect how light is transmitted?
How much light a material absorbs or lets through depends mainly on what kind of material it is. Usually pure substances will not absorb light but rather lets light through or reflects light. Exceptions include carbon, uranium and others. The exact theory goes into detail in how electrons absorb that energy and move to a higher orbital but generally, a material will let light through if the electrons require excessive energy to jump to a higher orbital.
Is wood transparent opaque or translucent?
Opaque means when an object does not allow light to pass through.

What colors are opaque?
Opaque is not a color. If something is opaque, it refers to how much light cannot travel through an object. Personally, I hear it used in reference to gemstones quite a bit. For instance, gemstones that are considered opaque include turquoise, opal, jade, etc.
How much light can the color white absorb?
White does not absorb light - it reflects all visible light waves, while black absorbs all visible light and reflects nothing.
How does the wavelength of gamma rays compare to the wavelength of visible light?
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.

How much sunlight do light colors absorb?
Less than dark colors.
