Spectrum, in optics, the arrangement according to wavelength of visible, ultraviolet, and infrared light. Spectra may be classified according to the nature of their origin, i.e., emission or absorption.

What do you mean by spectrum?
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 spectrum in simple word?
1: the group of colors that a ray of light can be separated into including red, orange, yellow, green, blue, indigo, and violet: the colors that can be seen in a rainbow beautiful scarves in all the colors of the spectrum. 2 technical: an entire range of light waves, radio waves, etc.
What is meant by spectrum of light?
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 spectrum of waves?
Wave spectra are used by oceanographers to describe the distribution of energy at different frequencies. The form of the spectrum can be related to wind speed and direction and the duration of the storm and the fetch (or distance upwind) over which it has blown,…
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 in human body?
The term spectrum has two different, but closely related, meanings. In general, the term refers to a whole range of things. The electromagnetic spectrum consists of forms of energy such as gamma rays, X rays, ultraviolet radiation, infrared radiation, visible light, radio waves, microwaves, and radar.
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.
How do you use the word spectrum?
Spectrum in a Sentence
- The survey provided the company with a wide spectrum of feedback on its products.
- At the medical clinic, we see a broad spectrum of patients from those who can pay something and those who can pay nothing.
- The insecticide is very powerful and can kill a wide spectrum of insects.
What are the 7 types of electromagnetic spectrum?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
What does spectrum mean in science?
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 are the 7 visible spectrum colors?
A commonly taught acronym that helps people remember the colors in the visible spectrum is ROY G BIV which stands for Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
What color has the highest frequency?
Violet waves have the highest frequencies. Red waves have the longest wavelengths.
What is Jonswap spectrum?
1. Wave spectrum typical of growing deep water waves developed from field experiments and measurements of waves and wave spectra in the Joint North Sea Wave Project. Learn more in: Wave Reflection at Submerged Breakwaters.
Why is it called the electromagnetic spectrum?
Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. If it has low frequency, it has less energy and could be a TV or radio wave. All EM energy waves travel at the speed of light.
