A unique continuous spectrum
Tungsten wire.
A continuous Spectrum
In an incandescent light bulb this is the filament. It is usually made of tungsten.
When light waves are emitted by moving source scientists can measure the Doppler effects. It is a source of energy that produces light.
The peak frequency is directly proportional to the absolute temperature of the emitter. Temperature increases frequency also increases.
One example is an incandescent light bulb. We normally use it for light, but it also generates a lot of heat.
Incandescent
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.

A continuous Spectrum
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.

Since white light is emitted from an incandescent bulb, it contains all wavelengths in the visible light spectrum between 400 to 700nm. It also emits wavelengths in the infrared region.
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
A element that produces light!
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
In an incandescent light bulb this is the filament. It is usually made of tungsten.
Tungsten is the most common element used as the filament in incandescent lightbulbs.
