Difference between tungsten lamps and carbon lamps?
tungsten lamp has got inert gas argonsometimes iodine is added to improve intensity carbon filament produces less light than tungsten lamp but it radiates much less energy in the form of heat waves
What is the purpose of halogen gas in a tungsten-halogen lamp?
because somebody didn't answer
What is the goop inside a lava lamp made of?
Water, wax, and carbon tetrachloride.
What is the difference between a metal halide lamp and a halogen lamp?
A halogen bulb is a traditional tungsten filament bulb filled with a noble gas that gives off a soft, yellowish light. In a metal halide bulb, the light emitted is bright white or even bluish. They have a longer life than halogen bulbs, but their brightness can diminish over time.
How do you get convention in a lava lamp?
The heat of the lamp causes the fluids to heat and expand. The two materials are of different thermal properties and are immiscible.The word you seek is convection.
What is the nature of the slope of the voltage-resistance characteristics for the carbon lamp?
for Tungsten lamp the slope of the curve is positive where for carbon it is negative

What material is used for fillament in tungsten lamp?

Which material is used for for filament in tungsten lamp?

What is lamp types?
There are two types of lamps the tungsten halogen lamps and incandescent lamps. Tungsten Halogen Lamps are similar to incandescent lamps and produce light in the same manner from a tungsten filament; however the bulb contains a halogen gas (bromine or iodine) which is active in controlling tungsten evaporation, whereas the incandescent lamp suppresses tungsten evaporation.
Why the lamp lights up?
Incandescence of a finely coiled tungsten wire.
What is the purpose of halogen gas in a tungsten-halogen lamp?

How many types of lamps are there?
There are many different types of desk lamp, ranging from lamps using traditional tungsten (or enerygy saving bulbs) to lamps using the more powerful halogen lamp. These are usually used where brighter light is required.
What is used to make globe filaments?
The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament. In 1906 the tungsten filament was introduced

What is a carbon arc lamp?
An arc lamp is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the early 1800s, was the first practical electric light.
Which lamp is used for projecting pictures in the cinema hall?
carbon arc lamp
