First, you need to define "light". Visible light only? Up into the ultra-violet? Down into infrared? Many filters wil block and/or reflect wavelengths above or below a certain cutoff point, while passing waves away from that point. As a for instance, a red filter will pass wavelengths from around 550 nm and longer, while it blocks anything shorter than 550. A green filter is a "notch" filter, in that it will only pass wavelengths from around 550 to around 500 nm. At the other end, a blue filter will block anything longer than about 500 nm, and pass shorter wavelengths, possibly up into the ultraviolet range.
That being said, nothing in this universe is perfect. No surface will reflect all wavelengths that land on it; any reflective surface will have some losses, both through what it allows to pass, and what it absorbs into itself, generally turning into heat. On the other end, the closest thing you might find to a "surface" that could absorb all light that falls on it would be a black hole.
something black and solid (not porous) eg. a black hole, black leather
All materials absorb (and emit) light. Characteristic wavelengths ("color" if they happen to be in the visible range) identify the material.
No material reflects all light. Silver is pretty close, which is why it is used for mirrors. As far as absorbing, porous black materials do the best job.
Opaque materials.
what kind of objects that absort light
black body
Co2
If you're asking for what light cannot touch, then there is nothing. Other than air, light acts on everything. If light did not reflect off of objects, they would be invisible. EDIT: Visible light cannot penetrate a mirror. If the mirror is of suitable quality, most of the light should be reflected, with the remainder being absorbed. EDIT: light acts on air, it does not act on a vacuum, it travels straight thru it. with air however, light is difracted
Well kind ojf he invents vackseen
Because some objects would be needed to be shown more than once, so you would have to use more than one kind of model.
Light has the property of being an electromagnetic wave.
compound light microscope
All objects do. There is none that does not absorb any.
Transparent objects are the sorts of objects that light passes through. Translucent objects allow the partial transmission of light. Opaque objects prevent the transmission of light.
Yes. All kind of sunglasses absorb some light. Some light is reflected too. Dark sunglasses absorb more than not so dark sunglasses.
Anything that reflects, absorbs, or scatters light can form some kind of shadow.
Luminous objects usually give out the light that they make on their own. An example of a luminous object is a star or an LED lamp.
transparent materials
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.
the sun not moon because moon has not light of itself

spectroscope.....find out what kind of atoms are giving off light energy
Materials which allow light to pass through are called transparent materials such as a plastic sheet, glass, air, acrylic sheet, water. etc. Opaque materials are materials which do not allow light to pass through such as wood, stone, black paper, paper bags, books, etc.
