when a current pass through a conductor it will heat it and raise its temperature, electrons will starts vibrating the conductor's atoms. Bound electrons in the vibrating atoms may be boosted temporarily to a higher energy level. When they fall back to their normal levels, the electrons release the extra energy in the form of photons. when a conductor is overheated it will melt down, tungsten is used in light bulbs since its meltdown temperature is very elevated. more than 90% of the released energy falls in the infrared range which is invisible to human eyes and only 10% of the emitted radiation is visible.

What element is in filaments?

Tungsten is the most commonly used element in filaments due to its high melting point and ability to emit light when heated. Alternatively, some filaments also use carbon or other metals like osmium or rhenium.


Is light in an incandescent bulb matter?

Yes, light in an incandescent bulb is a form of electromagnetic radiation, not matter. The light is produced by the heating of a tungsten filament in the bulb, causing it to emit visible light.


What metal does not decompose when heated with a Bunsen burner?

Tungsten is a metal that does not decompose when heated with a Bunsen burner due to its high melting point of 3422°C. This property makes tungsten ideal for use in the filament of incandescent light bulbs.


What does a tungsten filament do?

A tungsten filament is a key component in incandescent light bulbs. When an electric current passes through the filament, it heats up to a high temperature, causing it to emit light. Tungsten is used because of its high melting point and excellent conductivity, allowing it to glow brightly without melting. This process is known as incandescence, where the filament produces light as it becomes hot.


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

The filament inside a light bulb is typically made of tungsten, which is a poor conductor of electricity. When electricity flows through the filament, it encounters resistance, which causes the filament to heat up and emit light.

The element tungsten is ideal for use in light bulbs because of its?

Tungsten is ideal for use in light bulbs because of its high melting point, which is around 3422 °C (6192 °F).


Is a metal a source of light?

Answer No, not in itself. Metal can be used as a component in artificial light sources, and metal can be used to reflect light, but metal does not make light. Answer Metals, when heated to a certain temperature, can emit light. For example, Light bulbs have filaments of Tungsten in them. Electricity flowing through the Tungsten heats it up and it emits light.
