The bands of light and dark are classic signs of Gneiss (Gneissose banding), but Gneiss is not necessarily shiny. It may be sparkly, but not shiny. However, a Slate IS shiny, but does not have the pretty banding. Another consideration is Schist, which has similar characteristics to Gneiss.
My advise is that if you are classifying a rock that you are looking at, consider the grade of metamorphism, as it certainly is metamorphic. Also consider the mineralogy: what are the light and dark bands? Quartz, Feldspar (light)? Mica (biotite) (dark)? There are many possibilities. The mineralogy will help determine the original sedimentary rock, which you can then use to determine the metamorphic sample you have.
What else can I help you with?
How does the type of surface affect heating by radiation?
Dark matt surfaces absorb radiated heat much more easily than light-coloured shiny surfaces.
What is graphites luster?
Graphite exhibits a metallic to submetallic luster. This characteristic sheen is due to its layered structure, which allows light to reflect off the flat surfaces of the layers. The appearance can vary slightly depending on the purity and texture of the graphite, but it generally has a distinct, shiny quality that sets it apart from other carbon forms.
Is foil or white more reflective?
Foil is generally more reflective than white surfaces because of its smooth, shiny surface that can bounce light back more effectively. White surfaces may scatter light more than reflect it directly, causing some light to be absorbed rather than reflected.
What things emit and what things Reflect?
Things that emit include light bulbs, the sun, and fire, which release energy in the form of light and heat. Things that reflect include mirrors, glass windows, and shiny surfaces, which bounce light off them without absorbing it.
How does light interact with shiny metal?
It reflects the light, that is how the surface seems shiny.When light hits a shiny surface it is reflected and is sometimes bent.
What are shiny surfaces?
Shiny surfaces reflect light and appear smooth and glossy. They often have a polished or reflective finish that creates a mirror-like effect. Materials like metal, glass, and polished wood can have shiny surfaces.
Which description applies to matte surfaces?
Matte surfaces have a non-reflective finish, appearing dull and not shiny. They do not produce a glare or reflection of light, unlike glossy or shiny surfaces.
Can shadows be formed on shiny surfaces?
They couldn't shine AND have a shadow on them at the same time, as when something shines it is reflecting light. A shadow is an area where little/no light is reaching due to something between it and the light source.
Why does light reflect best on flat and shiny surfaces?
Light reflects best on flat and shiny surfaces because they provide a smooth surface for light waves to bounce off of without being scattered in different directions. This results in a clear and organized reflection, compared to rough or dull surfaces which scatter light in different directions, resulting in diffuse reflection.
Why do shiny surfaces better at reflecting light than rough surfaces?
Shiny surfaces have a smoother and more uniform texture, which allows light to bounce off more evenly, resulting in a clear reflection. In contrast, rough surfaces have uneven surfaces that scatter light in multiple directions, leading to a less defined reflection.
What surfaces reflect light and which do not?
Surfaces that are smooth and shiny, such as mirrors and glass, reflect light. Surfaces that are rough and dull, such as fabric and paper, do not reflect light as effectively. Rough surfaces scatter light in different directions instead of reflecting it.
Why do shiny surface do not absorb light?
Shiny surfaces do not absorb light because they have a smooth surface that reflects most of the light that hits them. This reflection prevents the light from being absorbed into the material, giving it a shiny appearance.
Why does something shiny stop heat radiation?
Types of light energy are reflected off of shiny surfaces back into the atmosphere. Other surfaces, such as darker ones, absorb the light energy and heat up much quicker.
Is it true that shiny materials absorb radiant energy?
I believe that shiny surfaces reflect radiant energy.
Do only shiny objects reflect light?
No, all objects reflect light to some degree, both shiny and non-shiny. Shiny objects tend to reflect more light due to their smooth and polished surfaces, while non-shiny objects may reflect less light and appear duller because of their rough or textured surfaces.
Which objects other then mirrors reflect light?
Anything shiny, such asjewelrysilverwareand glitter.Technically, everything reflects light because if nothing did, you couldn't see anything. But basically anything that is shiny "reflects" light.
Which surfaces don't reflect light?
Surfaces that do not reflect light well are typically rough or absorbent, such as black velvet or charcoal. These surfaces absorb most of the light that hits them, which is why they appear dark. Smooth and shiny surfaces, on the other hand, reflect light more efficiently.
