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.
What is the hypothesis for making a homemade lava lamp?
The hypothesis for making a homemade lava lamp could be that the combination of oil, water, and effervescent tablets (such as Alka-Seltzer) will create a visual effect resembling a lava lamp due to the reaction between the ingredients causing bubbles to rise and fall in the mixture.
What is the independent variable of a lava lamp?
The independent variable of a lava lamp experiment could be the temperature of the lamp, the type of wax or liquid inside the lamp, or the amount of time the lamp is switched on.
Why is oil needed in a lava lamp?
Oil is needed in a lava lamp to create a barrier between the water and the wax. This helps the wax rise and fall in a smooth and controlled manner, creating the mesmerizing lava lamp effect. Additionally, the oil helps to transfer heat efficiently, allowing the wax to melt and rise.
What is the manipulated variable in making a lava lamp?
The manipulated variable in making a lava lamp is the temperature of the lamp, which can be adjusted to control the movement of the colored blobs in the lamp.
What is the difference between a pole lamp and a normal lamp?
The difference between a pole lamp and a normal lamp is very miniscule. A pole lamp stands on a pole and the lights are strung up like they are on a tree.
What is the difference between compact fluorescent lamp and fluorescent lamp?
well one is spelled differently than the other
What light source does Spectrophotometry utilizes?
Spectrophotometry utilizes a light source such as a tungsten lamp, deuterium lamp, or xenon lamp to produce light at specific wavelengths. The light is then passed through a sample to determine its absorbance or transmittance at different wavelengths.
What is difference between R40 and BR40 light bulbs?
R40 is a Red Heat Lamp Light Bulb BR40 is a Clear Heat Lamp Light Bulb
What is the difference between MR11 and MR16 lamp fittings?
An MR-11 is about half the size if an MR-16.
Sources of light in a spectrophotometer?
In a spectrophotometer, the most common source of light is usually a tungsten-halogen lamp or a deuterium discharge lamp. Tungsten-halogen lamps emit a continuous spectrum of light, while deuterium lamps emit light in the ultraviolet region. These light sources provide the necessary illumination for the sample to absorb or transmit light, which is then measured by the spectrophotometer.

What light sources emits only a continuous spectrum a. hydrogen gas b. mercury lamp c. sodium lamp d. incandescent lamp e. laser?
d. incandescent lamp
What is the difference between LED and Energy Saver Lamps?
I am not sure. But what I know is that LED or LED lampen is an example of an energy saver lamp.
How is LED different from lamp?
similarity between lamp and LED- lamp in simple current is used to show that current is flowing and LED performs the same task but in electronic circuit .difference between lamp and LED-lamp in simple current is used to show that current is flowing and LED performs the same task more efficiently but in electronic circuit . so LED works more efficiently in electronic circuit than lamp which performs task in simple circuit.
What is the difference between a regular lamp and a children's lamp?
A children's night light or lamp is ment for use at night. Giving off just enough light to allow a child to enjoy the safely of the light and not fear the dark. While a normal lamp is ment for general use during the day, to light up a room.
What is the difference between 2 pin and 4 pin PL lamp?
The main difference between 2 pin and 4 pin PL lamps is the number of pins used to connect the lamp to the fixture. A 2 pin PL lamp has two pins for connection, while a 4 pin PL lamp has four pins. Additionally, 4 pin PL lamps typically have an integrated starter and ballast, while 2 pin PL lamps may require an external ballast.
