Sarcomere
The dark lines that appear in a spectrum of light from a star are called absorption lines. These lines are caused by the absorption of specific wavelengths of light by elements in the outer atmosphere of the star. Absorption lines help astronomers identify the chemical composition of stars and other celestial objects.
There are no bright lines and no dark lines in the spectrum, incandescent light has a continuous spectrum with all visible colors present
A spectroscope is a tool that separates a star's light into color bands and dark lines (absorption lines). These dark lines are produced due to the absorption of specific wavelengths of light by elements in the star's atmosphere. Spectroscopes are important in studying the composition and characteristics of stars.
The black lines (absorption lines) in a star's spectrum are caused by elements in the star's outer layers absorbing specific wavelengths of light. These elements absorb light at certain frequencies, creating dark lines by removing energy from the incoming light. By analyzing these absorption lines, scientists can determine the elements present in the star and study its properties.
Absorption lines are produced when elements in the outer layers of a star absorb specific wavelengths of light, leading to dark lines in the spectrum. These lines indicate the presence of certain chemical elements in the star's atmosphere. Absorption lines from a cool gas cloud between a star and Earth can reveal the composition, density, and temperature of the cloud, providing valuable information about the interstellar medium.
Sarcomere
The unit of alternating light and dark striations between Z lines in a muscle fiber is called a sarcomere. It is the functional unit of muscle contraction and is formed by the arrangement of thick and thin myofilaments within the sarcomere. The interaction between these myofilaments during muscle contraction results in the characteristic striations observed under a microscope.
Parallel lines seen on crystal faces or cleavage planes are called growth striations. They are caused by variations in the crystal's growth rate or conditions during formation, resulting in alternating layers of different densities or compositions. These striations can provide valuable information about the crystal's growth history and conditions.
The lines in an air wedge result from interference of light waves that have traveled different distances. The resulting interference pattern creates alternating dark and light bands. In Newton's rings, the circles are formed due to interference of light waves reflected between a convex lens and a flat glass surface. The varying thickness of the air gap creates a series of concentric circles of alternating dark and light fringes.
The scratch marks left on the proyectile by the rifling lines of the inside of the bore (barrel).
Skeletal Muscle (as well as Cardiac Muscle) have striations do to their sarcomere's anatomy. The sarcomere is the functional unit of the muscle and appears striated because the different thick and thin filaments present.
Narrow lines of colors with no light in between them are called dark lines. They are typically seen in the spectrum of light when certain wavelengths are absorbed or blocked.
Longitudinal striations are parallel lines or grooves that run along the length of a structure or surface, often seen in muscles or bones. They can provide information about the direction of muscle contractions or the growth patterns of bones.
In the sense that it makes it known that the rock existed before a period of glaciation, yes.
Power lines carry electricity as alternating current.
i believe that you are talking about glacial striations
Interlaced display is a type of cathode ray tube. The lines are in an alternating pattern that focuses on interwoven and rasterized lines.
