A linear emission spectrum is the collection of frequencies that a substance can emit when the atoms in it are excited (say, by heating) or can absorb. Where visible light frequencies are involved the emitted frequencies may be made to appear as a series of coloured lines on an axis representing frequency. Such a spectrum may also be represented as a series of dark lines presented against a straightened rainbow of colours where the axis along the edge of the rainbow represents light frequency.

No, an atomic emission spectrum is not a continuous range of colors. It consists of discrete lines of specific wavelengths corresponding to the emission of light from excited atoms when they return to lower energy levels. Each element has a unique atomic emission spectrum due to its unique arrangement of electrons.
The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.
A star's emission spectrum is a unique pattern of light emitted by the star, showing distinct wavelengths or colors of light. It provides information about the star's composition, temperature, and other properties. By analyzing the emission spectrum, astronomers can learn about the chemical elements present in the star and its physical characteristics.
The fluorescent light emission spectrum determines the colors produced by a fluorescent light source. Different elements in the phosphor coating of the bulb emit light at specific wavelengths, which combine to create the overall color of the light. The emission spectrum influences the perceived color of the light emitted by the bulb.
The white light emission spectrum is significant in optics and light sources because it contains all the colors of the visible spectrum. This allows for a wide range of applications, such as in color mixing, photography, and creating accurate color representations.
To identify an unknown sample by its emission spectrum
Bohr studied the line emission spectrum of hydrogen.
No, an atomic emission spectrum is not a continuous range of colors. It consists of discrete lines of specific wavelengths corresponding to the emission of light from excited atoms when they return to lower energy levels. Each element has a unique atomic emission spectrum due to its unique arrangement of electrons.
The emission spectrum of sodium lies in the yellow region of the visible spectrum, specifically around 589 nanometers.
The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
White light has a continuous spectrum with all wavelengths of light present, while the atomic emission spectrum of an element consists of specific wavelengths corresponding to the energy levels of the element's electrons. The emission spectrum is unique to each element and can be used to identify the element present.
Identify elements
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
No.
