What is meant by continuous spectra?

What is meant by continuous spectra?

Definition of continuous spectrum : a spectrum (as of light emitted by a white-hot lamp filament) having no apparent breaks or gaps throughout its wavelength range.

What is the difference between a continuous spectra and a discrete spectra?

General Types of Spectra For a continuous spectrum, the light is composed of a wide, continuous range of colors (energies). With discrete spectra, one sees only bright or dark lines at very distinct and sharply-defined colors (energies).

What is line and continuous spectra?

Continuous spectrum is a spectrum having all the wavelengths within a given limit whereas line spectrum is a spectrum having some lines of wavelengths within a given limit. Thus, continuous spectrum and line spectrum differ from each other according to the presence or absence of lines in the spectrum.

What is continuous energy?

“Continuous Energy spectra” in nuclear chemistry typically refers to the fact that kinetic energy of electrons (or positrons) released in beta decays can take any value from a specific range of energies.

What is a continuous spectrum give an example?

Continuous Spectrum. A rainbow is an example of a continuous spectrum. Here, the colors displayed are within the visible spectrum (between 380-760 nm). Light in this wavelength range is visible to the naked eye.

What is a continuous spectrum in astronomy?

Continuous spectra (also called thermal or blackbody spectra) arise from dense gases or solid objects which radiate heat. They emit radiation over a broad range of wavelengths, thus the spectra appear smooth and continuous.

Which of these is a continuous spectrum?

A rainbow is an example of a continuous spectrum. Most continuous spectra are from hot, dense objects like stars, planets, or moons. The continuous spectrum from these kinds of objects is also called a thermal spectrum, because hot, dense objects will emit electromagnetic radiation at all wavelengths or colors.

What is a continuous spectrum an absorption spectrum quizlet?

continuous spectrum is emitted by a “blackbody.” It consists of light of all wavelengths, but the amount of light emitted at each wavelength varies and depends on the temperature of the blackbody. absorption spectrum. An absorption spectrum is created when the light from a blackbody shines through a cooler gas.

What is the difference between line spectra and band spectra?

Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another. Band spectra is the name given to groups of lines so closely spaced that each group appears to be a band, e.g., nitrogen spectrum.

What do you know about the continuous spectrum?

The term continuous spectrum is mostly found in physics and mainly involves light and colors found therein. Spectra also help us understand how atoms absorb different light energies to provide the color we see. There are two main types of spectra. Continuous and line spectra and while these are generally different,…

Is it possible to have continuous and line spectra?

Continuous and line spectra and while these are generally different, it is possible to have both of them. Continuous spectrum can be learnt vividly in the context of light and electromagnetic spectrum. Here is a brief definition and description of these spectra as well as their differences:

Is the Rainbow in the sky a continuous spectrum?

Even though we see a rainbow in the sky when the sun shines after it rains, this is not actually a continuous spectrum. Most light in the universe (including light from the sun) is not a continuous spectrum but is instead either an absorption spectrum or an emission spectrum that we can see through a spectrometer.

Can a beam of white light contain a continuous spectrum?

A beam of perfectly white light, like you would get under certain laboratory conditions, contains this kind of spectrum. You can create a continuous spectrum by heating up a material until it glows.
