Saturn is the planet that will answer your question
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
dark brown and light brown
The wavy bands of light and dark minerals visible in gneiss likely formed from the process of high-grade regional metamorphism, where pre-existing rocks (such as granite or sedimentary rocks) were subjected to intense heat and pressure. This metamorphic process causes the minerals to recrystallize and segregate based on their composition, resulting in the characteristic banding. The light bands are typically rich in quartz and feldspar, while the dark bands are often composed of biotite, amphibole, or other mafic minerals. The wavy appearance of the bands can also reflect the dynamic conditions of deformation during metamorphism.
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.
Neptune's striped appearance is caused by a series of dark blue bands that circle the planet longitudinally. These bands are thought to be related to differences in the planet's atmospheric composition and circulation patterns. The exact mechanisms behind these bands are still being studied by scientists.
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.
The bands on Jupiter are areas of alternating light and dark clouds that are caused by differences in the planet's atmospheric composition and temperature. The most prominent bands are the equatorial bands and the polar bands, which are visible in Jupiter's atmosphere.

Yes, in striated muscle you can think of the "A" bands as the dArk bands and the "I" bands as the lIght bands.
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
Skeletal and cardiac muscle tissues are both considered as striated, which means that they have light and dark bands.
The alternation dark and light bands are found in muscles of humans and animals. They give the muscle fibers their striated appearance.
In striated muscle fibers, light bands (I bands) are formed by the protein actin, while dark bands (A bands) are formed by the protein myosin. These proteins play a crucial role in the sliding filament theory of muscle contraction.
A and I bands
The property of light responsible for producing dark and bright bands on the screen after passing through two slits is interference. When light waves pass through the two slits and overlap on the screen, they interfere with each other either constructively (bright bands) or destructively (dark bands) based on their relative phase.
No. Gneiss has alternating light and dark bands.
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
