What are the Dark lines that appear in a spectrum of light from a star called?
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.
What type of spectrum does an incandescent light produce?
There are no bright lines and no dark lines in the spectrum, incandescent light has a continuous spectrum with all visible colors present
What is a tool that separates a star's light into color bands and dark lines?
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.
Why do black lines appear on a star's absorption spectrum?
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.
How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?
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.
What is the unit alternating light and dark striations between the Z lines?
Sarcomere
Unit of alternating light and dark striations between z lines?
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.
What are the parallel lines seen on crystal faces or cleavage planes?
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.
Why there are lines in air wedge and circles in newton's rings?
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.
What are bullet striations?
The scratch marks left on the proyectile by the rifling lines of the inside of the bore (barrel).
Striations of skeletal muscle are produced by?
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 what?
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.
What is longitudinal striations?
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.
Why do glacial striations show the direction a glacier moved?
In the sense that it makes it known that the rock existed before a period of glaciation, yes.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
Marked with parallel scratches or grooves?
i believe that you are talking about glacial striations
What is interlaced display?
Interlaced display is a type of cathode ray tube. The lines are in an alternating pattern that focuses on interwoven and rasterized lines.
