In 1909, Ernest Rutherford fired alpha particles (helium nuclei) at a very thin sheet
of gold foil. Many of the alpha particles passed through but some were deflected
at an angle and some surprisingly bounced back. This experiment showed that the
atom had a dense but very small positive core, the electrons were far away from
the very small positive core (nucleus), and the electrons were separated from the
nucleus by a lot of empty space. The atom is more than 99.999999% empty space!
Like clear glass insulators, it seems that everything should be transparent to visual
light. However, metals have a loose sea of electrons that makes visible light bounce
back and the metal appears shiny. For opaque objects like metals, most of the light
is either reflected by the object or absorbed and converted to heat. For transparent
objects like air and clear glass, the light travels through it.
Another contributor passes through and pauses to observe:
The question is perplexing. It starts off by asserting glibly that insulators ...
which in my experience includes wood, rubber, and concrete ... are transparent
to visual light.
Seems to me that if insulators were transparent to visual light, then we would
always be able to see every conducting wire inside a cable of many wires, since
each and every one is covered in an insulating jacket.

Do you use hair to make a light bulb?
No, hair is not used to make a light bulb. Light bulbs are typically made of glass or other transparent materials, with a filament made of tungsten or other metals that produce light when heated. Hair is not a suitable material for this purpose.
Is Styrofoam transparent?
No, Styrofoam is not transparent. It is an opaque material, meaning that light does not pass through it easily and it is not see-through.
Why are some seas transparent?
Water is not totally transparent. Some light gets absorbed when it passes through water. The longer the distance, the more light gets absorbed.Water is not totally transparent.

How do you use transparent in a sentence?
Transparent tape was originally made from celluloid. All of the windows were transparent except the one in the bathroom. His motives for passing the law were transparent to his colleagues.
What is the noun form of the word transparent?
The noun form of the word "transparent" is "transparentness." Transparentness can be defined as the state of transmitting light rays through its substance.
Why insulators are transparent?
Insulators are transparent because they have a wide energy band gap that does not allow electrons to move freely and absorb light. When light passes through an insulator, it interacts with the atoms in a way that does not result in the absorption of photons, thus allowing light to transmit through the material.
What is the opposite of transparent?
The visual and optical opposite of transparent is "opaque."Metaphorically, the description of motives as transparentwould have the opposites unclear or hidden.
What are physical properties of non metals?
Non metals do not conduct heat & electricity, good insulators, non mileable, high combustivity, low density and light in weight
Is opaque a color?
No. 'Opaque' is a term meaning impenetrable by light; neither transparent nor translucent.
Non transparent materials?
Non-transparent materials do not allow light to pass through them, making them opaque. Examples include metals, wood, and ceramics. These materials absorb or reflect light rather than transmitting it.
What is the transparent outer layer of the eye called?
Sclera
Is glass transparent translucent or opaque?
No, such a transparent metal is not possible. Metals are a conductor of electricity. As a result of this, electromagnetic waves of the wavelength of light cannot penetrate it.
What word is used for materials that light can pass through?
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
Is there a transparent metal?
Yes, there are transparent metals. Materials like aluminum, indium tin oxide, and some metal oxides can be engineered to be transparent by controlling the arrangement of their atoms to allow light to pass through while still maintaining their metallic properties. These transparent metals have applications in electronics, optics, and coatings.
What word lets all light pass through?
The word you're looking for is "transparent." Objects that are transparent allow light to pass through them without scattering the light.
How light is affected by a transparent object?
It isn't, unless the transparent object has shape. In that case, the light will be refracted.
What media can let sound or light wave through?
Materials such as air, water, glass, and certain metals can allow sound or light waves to pass through them. These materials are known for their transparent or translucent properties, which enable the transmission of sound or light.
