Black lines on a star's spectrum represent absorption lines, which occur when specific wavelengths of light are absorbed by elements in the star's atmosphere. Each line corresponds to a particular element or molecule, indicating the presence of those substances. The colors associated with these lines are typically seen as dark bands against the continuous spectrum of light emitted by the star. Analyzing these absorption lines allows astronomers to determine the star's composition, temperature, and other properties.
The emission spectrum of the sun is primarily a continuous spectrum with dark absorption lines, known as the Fraunhofer lines, which occur at specific wavelengths where elements in the sun's atmosphere absorb light. This spectrum reveals the presence of various elements, including hydrogen, helium, calcium, and iron, as each element absorbs light at characteristic wavelengths. By analyzing these absorption lines, scientists can determine not only the composition of the sun but also its temperature, density, and other physical properties. Overall, the sun's emission spectrum serves as a crucial tool in astrophysics for understanding stellar composition and behavior.
Gaps in a continuous spectrum refer to specific regions or wavelengths where no emission or absorption lines are present. These gaps occur because certain energies or wavelengths are not allowed for an atom or molecule to emit or absorb, resulting in a discontinuity in the spectrum. These gaps can provide valuable information about the energy levels and properties of the atoms or molecules being studied.
The light from the Sun produces a continuous spectrum, which appears as a smooth gradient of colors from red to violet. This spectrum is primarily due to the thermal radiation emitted by the Sun's surface, which behaves like a blackbody radiator at a temperature of about 5,500 degrees Celsius. Additionally, the Sun’s spectrum contains dark absorption lines, known as Fraunhofer lines, which occur when specific wavelengths of light are absorbed by elements in the Sun's atmosphere. These lines provide valuable information about the Sun's composition and the physical conditions in its outer layers.
Atomic spectra refer to the distinct lines of light emitted or absorbed by atoms when electrons transition between energy levels. There are two main types of atomic spectra: emission spectra, which are produced when electrons fall to lower energy levels and release energy as photons, resulting in bright lines on a dark background; and absorption spectra, which occur when electrons absorb energy and move to higher energy levels, showing dark lines on a continuous spectrum. Each element has a unique atomic spectrum, acting like a fingerprint for identification.

The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
