7 Why does a deuterium lamp produce a continuous rather than a line spectrum in the UV?

To answer this question, let's think about the excitation and relaxation processes involved. In the excitation process inside a deuterium lamp, an electrical arc between an oxide coated filament and an electrode excites D2 to D2*. Next, the D2* dissociates into individual D atoms. Let's call these D' and D''. Also, a photon of light is released. For an individual event, the total energy posssessed by D2* is apportioned between the kinetic energies of D', D'', and the photon. The sum of the kinetic energies of D' and D'' can vary from almost zero to the original energy of D2*. If the kinetic energies of D' and D'' are relatively small, the energy of the photon is large, and a shorter wavelength of light is emitted. If the kinetic energies of D' and D'' are relatively large, the energy of the photon is small, and a longer wavelenght of light is emitted. In a population of D2*, a distribution of kinetic energies of D' and D'' will result, allowing for a continuum spectrum to be emitted from the lamp.

Is D2SO4 concentrated sulfuric acid?
D2SO4 would be sulfuric acid with deuterium rather than hydrogen atoms. It can be as concentrated as you want. It's used to deuterate solvents like benzene and chloroform for use in nuclear magnetic resonance spectrography.
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
Why does the alkali-catalysed hydrolysis of an ester produce a sodium salt rather than a carboxylic acid?
An acid can not survive in a basic medium. CH3-COOH + NaOH -------> CH3-COONa + H2O
How a strong acid and a weak acid behave differently when each is dissolved in water?
The strong acid could cause an exothermic reaction (produce a lot of heat) Weak acid do the same, but do not produce such a strong exothermic reaction. Acid in Water might be a thrill Water in Acid could be rather unpleasant. Regards.
How do you test metal?
You can heat it, put it in acids and bases, try to combine it with other metals, and measure physical properties like density, specific heat capacities (which can be considered thermal rather than physical), ductility (whether it deforms), and cleavage (how it breaks). You can also try to burn it or heat it and view its light spectrum (spectrophotometry).
Why is the emission spectrum of hydrogen a line spectrum and not a continuous spectrum?
It's a line spectrum because of the quantization of energy- meaning you only see energy with levels n=1,2,3.... One would never see the energy level n=2.8 for instance- that would be the case if it were continuous rather than a line spectrum.
What is the most common typle of nuclear fusion in the sun?
The most common fusion in the sun is two hydrogen atoms fusing to produce helium. There are different ways this can happen. Two deuterium atoms may fuse, or a deuterium atom may fuse with a tritium atom, or two tritium atoms may fuse. Since the half life of tritium is rather short, the overwhelming majority of these atoms are deuterium atoms. The commonest form of hydrogen, known as protium, does not take part in the process.
Can you give a sentence with the word spectrum?
The company provides a rather wide spectrum of products.The word spectrum was introduced into the field of optics during the 17th century.
What is the difference between a continuous spectrum an a line spectrum?
Dispersion, the separation of visible light into a spectrum, may be accomplished by means of a prism or a diffraction grating. Each different wavelength or frequency of visible light corresponds to a different color, so that the spectrum appears as a band of colors ranging from violet at the short-wavelength (high-frequency) end of the spectrum through indigo, blue, green, yellow, and orange, to red at the long-wavelength (low-frequency) end of the spectrum. In addition to visible light, other types of electromagnetic radiation may be spread into a spectrum according to frequency or wavelength. The spectrum formed from white light contains all colors, or frequencies, and is known as a continuous spectrum. Continuous spectra are produced by all incandescent solids and liquids and by gases under high pressure. A gas under low pressure does not produce a continuous spectrum but instead produces a line spectrum, i.e., one composed of individual lines at specific frequencies characteristic of the gas, rather than a continuous band of all frequencies. If the gas is made incandescent by heat or an electric discharge, the resulting spectrum is a bright-line, or emission, spectrum, consisting of a series of bright lines against a dark background. A dark-line, or absorption, spectrum is the reverse of a bright-line spectrum; it is produced when white light containing all frequencies passes through a gas not hot enough to be incandescent. It consists of a series of dark lines superimposed on a continuous spectrum, each line corresponding to a frequency where a bright line would appear if the gas were incandescent. The Fraunhofer lines appearing in the spectrum of the sun are an example of a dark-line spectrum; they are caused by the absorption of certain frequencies of light by the cooler, outer layers of the solar atmosphere. Line spectra of either type are useful in chemical analysis, since they reveal the presence of particular elements. The instrument used for studying line spectra is the spectroscope.
Are molecules inside the solid stationary or in a continuous motion?
Continuous vibration rather than motion, but not stationary. Unless the temp drops to absolute zero.
Continuous random variables are obtained from data that can be measured rather than counted?
true
What is a semi continuous reactor?
I think you will find this in Chemistry rather than nuclear energy
Why communication is continuous process?
Communication is not an art or event at an instance of time rather it is a continuous process, incorporating various events and activities that are inter-related and inter-dependent.
Why does the world appear smooth and continuous rather than grainy as described by quantum physics?
The world appears smooth and continuous because we are not sensitive to the small scale microworld of the quanta
How are extremists at opposite ends of the political spectrum similar?
Frequently their actions are guided by 'What they CAN do' rather than 'What they SHOULD do'.
How do you arrange the 7 electomagnetic waves in order of increasing of their wavelength?
There are not "7 electromagnetic waves". The electromagnetic spectrum is a continuous one, without any divisions.Many people, engineers and experimental physicists in particular, paste some rather wide labels on parts of the EM spectrum. This is done for their convenience, and mostly is a flexible classification. There are no divisions of the actual spectrum.Having said that, the common classification is :-gamma rayshard X-rayssoft X-raysfar ultravioletultravioletvisible lightinfraredfar infraredmillimeter wavesmicrowavesUHFVHFHFMFLFULF
Is gamma has the pure energy rather than alpha and beta?
They are all forms of energy. A part of the electro-magnetic spectrum
