Atomic spectra is the study of atoms (and atomic ions) through their interaction with electromagnetic radiation. We all know about the refraction of light. The speed of light depends upon the nature of the medium through which it passes. ...
What is spectrum in chemistry class 11?
This is the phenomenon that gave serious blow to Rutherford model.It can be defined as: ‘ splitting of light’ into various colours or colour bands is called spectra.” When we see VIBGYOR the Violet colour merges into another and likewise other color merges into another. ... The study of spectra is called spectroscopy.
What is spectrum in BYJU’s?
Atomic spectra is the study of atoms (and atomic ions) through their interaction with electromagnetic radiation. We all know about the refraction of light. The speed of light depends upon the nature of the medium through which it passes. ...
What is meant by spectrum in chemistry?
Updated July 03, 2019. A spectrum is defined as the characteristic wavelengths of electromagnetic radiation (or a portion thereof) that is emitted or absorbed by an object or substance, atom, or molecule . Plural: Spectra.
What is spectrum and its types?
When electromagnetic radiation is passed through a prism or grating it is split up and forms a collection of lines representing different wavelengths. This is called spectrum. The spectra can be divided into two types viz., emission and absorption spectra .
What is spectrum with diagram?
A spectrum is simply a chart or a graph that shows the intensity of light being emitted over a range of energies .
Is color a spectrum?
| colour* | red | wavelength (nm) | 650 | frequency (10 14 Hz) | 4.62 | energy (eV) | 1.91 |
|---|
What is spectrum How is spectrum obtained Class 11?
When the radiations emitted from some source eg: from the sun or by passing electric discharge through a gas at low pressure or by heating some substance to high temperature is passed directly through the prism and then received on the photographic plate, the spectrum obtained is called emission spectrum.
How line spectrum is formed?
Spectral lines are produced by transitions of electrons within atoms or ions . As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed....
What is spectrum explain briefly?
A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum . The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.
What is another name for spectrum?

What is normal spectrum?
a representation of a spectrum arranged upon conventional plan adopted as standard, especially a spectrum in which the colors are spaced proportionally to their wave lengths, as when formed by a diffraction grating.
What is hydrogen spectrum explain?
The hydrogen spectrum is an important piece of evidence to show the quantized electronic structure of an atom . ... It results in the emission of electromagnetic radiation initiated by the energetically excited hydrogen atoms. The hydrogen emission spectrum comprises radiation of discrete frequencies.
What are the three types of spectrum?
- Continuous spectrum.
- Line spectrum and.
- Band spectrum.
What does spectrum mean in telecom?
Spectrum is the life-blood of a telecom operator – it’s literally a range of electromagnetic waves , and when we talk about telecom spectrum, we’re talking about the frequencies that are used to transmit sound and data across the country to our phones. ... The allotment of spectrum is either paired or unpaired.
What type of spectrum is hydrogen spectrum?
The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum , at 656 nm.
