How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
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.
Which absorption spectrum is equivalent to a fingerprint of a substance?
The UV-Vis absorption spectrum is often referred to as the fingerprint of a substance because it provides a unique pattern of absorption peaks and intensities that is specific to that substance. This spectrum is commonly used to identify and characterize unknown compounds in chemistry.
What Is The Absorption Spectrum Of boron?
The absorption spectrum of boron typically shows strong absorption in the ultraviolet region, with some absorption in the visible spectrum as well. Boron's absorption spectrum is characterized by a series of sharp peaks due to transitions between energy levels in its atomic structure.
Does the Sun produce a continuous spectrum or an absorption spectrum?
The photosphere of the sun doesn't really produce a continuous spectrum; there are discontinuities corresponding to energy levels of various chemical elements, called spectral lines. Notably Helium was discovered in the absorption lines of the solar spectrum and only later discovered on Earth.
What is meant by the absorption spectrum of a pigment?
The absorption spectrum of a pigment refers to the range of wavelengths of light that the pigment can absorb. It is typically represented graphically with absorption peaks indicating which wavelengths of light are absorbed most strongly by the pigment. The absorption spectrum is important in understanding the color of the pigment because the color we see is determined by the wavelengths of light that are not absorbed but reflected or transmitted.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
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.

What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
Uv spectra of aniline?
Aniline shows absorption peaks in the ultraviolet region around 210-220 nm due to its benzene ring structure. The spectrum can be used for identification and quantification purposes in analytical chemistry. The exact UV spectrum of aniline may vary depending on its concentration and solvent used.
What is the difference between an absorption and an emission spectrum?
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
How absorption spectrum is obtained?
An absorption spectrum is obtained by passing light through a material and measuring the amount of light absorbed at each wavelength. The absorption spectrum shows the absorption of light by the material at different wavelengths, providing information on the electronic structure and composition of the material. This technique is commonly used in various fields such as chemistry, physics, and biology to study the properties of different substances.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
What is the definition of Spectrophotometry?
The term "Spectrophotometry" refers to an instrument that is often used to determine the intensity of the various wavelengths in a spectrum of light. This tool is a part of analytical chemistry.
What Is The Absorption Spectrum Of boron?

What meant by an absorption spectrum?
In the absorption spectrum the peaks are due to preferential absorption at a definite wavelength by molecules, ions, etc.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
