What is the difference between a continuous spectrum and a line spectra?
A continuous spectrum consists of all wavelengths within a certain range. This spectrum looks like a rainbow. In contrast, a line spectrum only consists of a few wavelengths. This spectrum is made of a few colored lines on a dark background.
Is line spectrum continuous or discontinuous?
Each packet of energy corresponds to a line in the atomic spectrum. There is nothing between each line, so the spectrum is discontinuous.
What is the difference between continuous and absorption spectrum?
Emission Spectra Vs Absorption Spectra: The emission spectra are obtained due to radiations emitted by excited atoms. The absorption spectra are obtained when atoms absorb energy. It is a continuous spectrum, consisting of all the wavelengths having dark lines between them.
What does a continuous spectrum do?
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.
What is the difference between a line spectrum and a continuous spectrum quizlet?
Line spectrum is produced by excited atoms in the gas phase & contain only certain frequencies; all other frequencies would be absent. Continuous Spectrum is emitted radiation that contains all frequencies.
Why do solids give continuous spectra?
In solids atoms are not free but they are packed so tightly that their orbits overlap with each other. The energy changes in a particular atom are impacted by the other atoms in the surrounding. The impact is the radiations of all wavelengths are emitted. Therefore, solids give rise to continuous spectra.
What’s the difference between line spectrum and continuous spectrum?
Continuous spectra vs. line spectra. Line spectrum can also be generated in emission and absorption spectrum while continuous spectrum occurs when both absorption and emission spectra of a single species are put together. In other words, line spectrum can be in either emission spectrum or absorption spectrum.
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:
Are there any gaps in the continuous spectrum?
A truly continuous spectrum should not have any gaps and identifying gaps in the sun’s light is how scientists know what it is made of. The absorption gaps detail other elements including hydrogen and helium. Rainbow is generally accepted as an example as it details all the colors (wavelengths) from red to violet without any gaps.
Is there a continuous spectrum in a rainbow?
Those who have seen a rainbow have probably seen a continuous spectrum as it is agreed that the sun’s light contain this kind of spectrum although you will learn that this is not so all the time.
