Distinguish between an absorption spectrum and an emission spectrum.with which did bohr work?
In absorption spectra, one works with measuring the amount of energy absorbed when an electron moves from a lower to a higher energy level. In emission spectra, one works with the energy emitted when an electron moves from a higher to a lower energy level. Niels Bohr worked with emission spectra.
He worked on emission Spectra
Well, an absorption spectrum is like going to an all-you-can-eat buffet, where the atoms in a substance absorb specific wavelengths of light and leave gaps in the spectrum. It's like atoms saying, "Mmm, that color looks delicious, I'll have some of that!"
On the other hand, an emission spectrum is like a fireworks show, where excited atoms release energy in the form of light, creating bright lines at specific wavelengths. It's like atoms going, "Woohoo, party time! Let's light up the night with these flashy colors!"
Now, Mr. Niels Bohr, the man himself, worked with the emission spectrum. He discovered that when electrons in atoms jump to lower energy levels, they emit specific amounts of light, helping us understand the structure of atoms. So Bohr was all about those fancy light shows!
An absorption spectrum and an emission spectrum are two different types of spectra that provide different information about the interaction between light and matter.
1. Absorption Spectrum:
- An absorption spectrum is produced when a sample absorbs specific wavelengths of light from a continuous spectrum.
- It appears as a continuous spectrum with a series of dark lines called absorption lines or bands.
- These dark lines represent the wavelengths of light that have been absorbed by the sample's atoms or molecules.
- Absorption spectra are obtained when a continuous spectrum of light passes through a sample, and certain wavelengths are absorbed by the sample material.
2. Emission Spectrum:
- An emission spectrum is produced when a sample emits light after being excited by an external energy source.
- It appears as a series of bright lines or bands against a dark background.
- These bright lines correspond to specific wavelengths of light that are emitted by the excited atoms or molecules.
- Emission spectra are obtained when a sample is excited by heat, electricity, or certain other energy sources, causing its atoms or molecules to enter excited states and subsequently emit light.
Niels Bohr, the Danish physicist, worked primarily with emission spectra. His famous model of the atom, known as the Bohr model or Bohr's theory of atomic structure, explained the spectral lines observed in the emission spectra of hydrogen atoms. It proposed that electrons occupy specific energy levels within an atom and can jump between these levels by either absorbing or emitting energy in the form of discrete packets called quanta or photons.
An absorption spectrum and an emission spectrum are two distinct types of spectra that are related to the interaction of light with matter.
An absorption spectrum is obtained when a sample of a material absorbs light of various wavelengths. It is produced when a continuous spectrum of light passes through a material, and certain wavelengths are absorbed by the atoms or molecules within the material. The absorbed energy promotes electrons to higher energy levels within the atoms or molecules, resulting in the dark lines or bands observed in the spectrum. Each element or compound has a unique absorption spectrum, allowing scientists to identify their presence in a sample.
On the other hand, an emission spectrum is obtained from a sample of a material when it emits light of specific wavelengths. It is produced when atoms or molecules in an excited state return to lower energy levels and release energy in the form of light. The emitted light appears as a series of bright lines or bands at specific wavelengths, which are characteristic of the element or compound being studied.
Niels Bohr, a Danish physicist, mainly worked with emission spectra. His pioneering work in the early 20th century led to the formulation of the Bohr model of the atom, which explained the nature of energy levels and transitions within atoms. Bohr's model provided a theoretical framework for understanding the emission spectra of atoms and helped to develop our understanding of atomic structure and quantum mechanics.
