No. A Tungsten light is an incandescent lamp with its filament made from tungsten.

Strictly speaking there is no such thing as a Fresnel light. There is a Fresnel lens, which is a lens whose surface has concentric ridges rather than a smooth surface like a normal lens. Although fairly useless for looking at things, it is cheaper, smaller and lighter way of concentrating the output of a lamp into a narrow beam. These are often found in lighthouses.

Why does tungsten heat and light up but copper wire does not?

Copper has much less resistance, so the electricity flows thru it with little heat, where as the tungsten resists the flow and generates heat, that you see as light.


What makes a light bulb glow when a lamp is turned on?

In an incandescent light bulb a small coil of thin tungsten metal - which is not such a good conductor of electricity as copper - resists the flow of current so much that it heats up. The thickness of the tungsten is carefully designed so that it gets hot enough to give out visible light but does not get so hot that it melts and breaks.Another answerInside the bulb is a wire that goes to a piece of coiled tungsten (a heavy metallic element). This causes maximum resistance to the electricity flowing through the wire. The resistance causes the tungsten to heat up to 4,500 degrees F, so much that we see the glow as light. The glass bulb surrounding it contains an inert gas, protecting the filament from oxygen which would cause it to burn out immediately and also prevents contact with the white hot metal.For more information please click on the Related Questions shown below.


Is the tungesten filament a good conductor?

Tungsten is a good conductor of electricity. If it was a poor conductor and highly resistive then electricity would never pass through it as a filament inside a light bulb, therefore, it would never glow.


Why is the filament of a light bulb made from tungsten?

Tungsten is used because it has the highest melting point of all the metallic elements. It melts at 3410 degrees Celsius. When current passes through the filament it heats it up. When the filament reaches a certain temperature it starts to give off light, that's how you get a light bulb.

What are the substances in tungsten?

There are none, tungsten is a pure element so it is made of only tungsten.


What are the advantages of led light units compared to tungsten light units?

They use less power and don't give off so much heat.


What elements make up Tungsten?

Tungsten is an element and so is composed of tungsten atoms


The part of a light bulb that is a poor conductor so that the friction causes it to light up and glow?

That part of a light bulb that causes light to light up is called the filament, and it is typically made from tungsten.


Light bulbs how does running electricity through the bulb create light?

The electricity runs through a coil of Tungsten. Tungsten has a very high resistance. As per Joule's Law, energy radiated is directly proportional to resistance. The energy radiated is so large that the coil starts to glow and light is produced.


What are so uses of the element tungsten?

its used in light bulbs and high power tools that are used in high heated areas.


Is the fresnel biprism experiment better than young's double slit experiment?

yes,because in fresnel biprism the fringe width can be increased so that the dark and bright fringes can be seen clearly by naked eyes..but there is no such problem in fresnel biprism.. in young's double slit experiment, the pattern is the superposition of interference and diffraction. but in fresnel biprism it is purely interference pattern.


What countries use tungsten?

Tungsten in the form of Tungsten carbide is widely used in masonry drill tips, and in paint scrapers for handymen. It has a significant use in the filament of incandescent light bulbs. As a weld application, it may be used as a hardening on the cutting edge of the blades of bulldozers, and excavator buckets. So very few countries would not use tungsten.


Is there a such thing as a tungsten suit?

no,Tungsten is incredibly heavy so its impossible for a human to carry it


What does W stand for in Tungsten?

Tungsten was originally called 'Wolfram' - so was given the letter W to represent it.


Why tungsten bulbs use up so much energy?

90% of the energy used by a tungsten lamp is lost as heat because they depend on heating the filament until it gives off light. Only 10% is usable light.A 100 watt light bulb gives off 341 btu of heat.
