What is the difference between a continuous and an emission spectrum?
What is the difference between emission spectrum and continuous spectrum? The continuous spectrum is a continuous bright region with all the wavelengths of the selected region present. An emission spectrum has only bright lines in a wide dark region corresponding to the photons absorbed and emitted by the electrons.
What is continuous & discontinuous spectrum?
A continuous spectrum contains every wavelength between the wavelength on which the spectrum starts and the wavelength on which the spectrum ends. A discontinuous spectrum is a spectrum that contains gaps, holes, or breaks in terms of the wavelengths that it contains.
What is continuous spectrum and line spectrum in chemistry?
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.
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 causes a continuous spectrum?
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 continuous spectrum Class 11?
1)Continuous spectrum When white light from any source is analysed by passing through a prism, it is observed that it splits up into 7 different wide bands of colour. These colours are so continuous that each of them merges into the next. Hence the spectrum is called continuous spectrum.
How is continuous spectrum obtained?
Hint: Continuous spectrum is mainly produced by thermal emission from a blackbody. Only certain wavelengths can be emitted and absorbed by the atom when the energy levels in the atom are quantized.
Is sunlight a continuous spectrum?
The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. This type of spectrum is called an emission spectrum because what you are seeing is the direct radiation emitted by the source.
What is meant by continuous energy?
Energy in general is continuous, in the sense that any value of the energy can be measured. However, for systems such as the electrons in atoms which are stable, only certain energies are permitted. The permitted energies are discrete, not continuous.
