A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without gaps, 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 known as spectrum?
A group of wavelength and frequency is known as spectrum .
What does it mean to be in a spectrum?
Professionals and laypeople alike refer to children who are on the spectrum meaning they have some form or degree of autism. Where your child falls on this spectrum means they exhibit different behavioral patterns. Classic autism, or autistic disorder, is the most severe of the autism spectrum disorders.
What is a spectrum example?
Spectrum is the range of colors of wavelength energy sent out from a light source when viewed through a prism. An example of a spectrum is a rainbow. The range of electromagnetic radiation (electromagnetic waves) in our known universe, which includes visible light.
What is a spectrum Class 10?
Spectrum:The band of colours obtained on a screen on passing white light through a prism is called spectrum. The prism has split the incident white light into a band of colours. The various colours seen are Violet, Indigo, Blue, Green, Yellow, Orange and Red.
What is a spectra in chemistry?
A spectrum is a graph that shows the intensity of radiation at different wavelengths or the response of the atomic or molecular system to different wavelengths of the radiation. Examples of absorption and fluorescence spectra are shown in Figures 1. 1 and 1. 2.
What is a spectrum answer?
The spectrum is the range of different colours which is produced when light passes through a glass prism or through a drop of water. A rainbow shows the colours in the spectrum.
What is the spectrum Urban Dictionary?
This is the Urban Dictionary example sentence for “on the spectrum,” which is defined as “a phrase used to describe a person with social tics and/or awkwardness usually associated with autism or Asperger’s Syndrome.”
What is another name for spectrum?

What is spectrum and its type?
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. Examples of a spectrum include the rainbow, the emission colors from the Sun, and the infrared absorption wavelengths from a molecule.
What is spectrum in chemistry class 11?
Class 11 Chemistry Structure of Atom. Emission And Absorbtion Spectra. EMISSION AND ABSORBTION SPECTRA. Atomic spectra: Absorption and Emission spectra. 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.”
What is a spectrum Class 7?
Answer: The band of seven colors obtained, when a white light splits into its constituent colors on striking the surface of glass prism is called as a spectrum.
What is a spectrum in physics?
spectrum, in optics, the arrangement according to wavelength of visible, ultraviolet, and infrared light. An instrument designed for visual observation of spectra is called a spectroscope; an instrument that photographs or maps spectra is a spectrograph.
What is a spectrum Class 8?
Answer: The term spectrum refers to the order and arrangement of different colours of light constituting the white light. A glass splits white light into its constituent colours because different colours of light have different angles of deviation.
What is spectrum by Topper?
The band of colours (VIBGYOR) seen on passing the white light through a prism is called the spectrum.
What is spectrum and Spectroscopy?
The science of spectroscopy is quite sophisticated. From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star. The width of the line can tell us how fast the material is moving.
What is origin of spectra?
Line spectra are of varying degrees of complexity and have their origin in atoms. All compounds which can be excited to luminosity without decomposition give rise to band spectra, but the application of sufficient energy results in the appearance of the spectra of the component elements.
What are the 3 types of spectra?
There are three general types of spectra: continuous, emission, and absorption. Each is characterized by a different distribution of the wavelengths (i.e., colors) of radiation.
What is the definition of spectrum in biology?
noun. Botany. The relative numbers of plant species per biological type (as aerophytes, hygrophytes, phanerophytes, etc.) occurring in a particular ecosystem, each expressed as a percentage of the total.
What is a spectrum in astronomy?
A spectrum is a plot of light intensity or power as a function of frequency or wavelength. Spectra is used to determine what stars, nebula and galaxies are made up of.
What is linear spectrum?
quantum theory
atoms is known as a line spectrum, because the radiation (light) emitted consists of a series of sharp lines. The wavelengths of the lines are characteristic of the element and may form extremely complex patterns.
