Dispersing light from a hot wire which emits white light gives what type of spectrum is it?

A hot, glowing wire emits all wavelengths (or colors) of light. This is sometimes called "blackbody radiation." Since all colors are present, you will get a continuous spectrum.

What spectum is obtained When any element in the gas phase is excited to the point where it emits visible light?
When any element is excited to the point where it emits visible light, it emits a unique spectrum. The mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.
Light 489 nm Where is this on the electromagnetic spectrum If it is visible light what color Another laser a diode laser emits light 987 nm Where is this on the electromagnetic spectrum?
Light at 489 nanometers is in the blue area of the spectrum. Use the link below for more information.
What are the different color spectra of a LED?
A single LED emits light at one single frequency, so it has no spectrum.
Most sunlight consists of what parts of the electromagnetic spectrum?
The visible spectrum (the radiation we can see as light). This is most likely why organisms evolved to be able to see visible light over other types of electromagnetic radiation - the sun emits this more than the other frequencies, so it was easier for life to evolve seeing this spectrum.
What is the relationship between visible light spectrum and your sight?
Sight can only be possible in the presence of light. To be able to see an object, we either see the light which it emits, if it is a luminescent object, or the light which reflects off it, if it is a non luminescent surface.
What does a star emits?
The spectrum is a kind of analysis of the light emitted by a star.

The hot Gas in Star Formation Regions emits light because of?
A star emits light because it is hot enough to emit electromagnetic waves in the visible spectrum.
What r d differences between spectrometer and spectrograph?
spectrometer is a device that gives the spectrum of all intensities of a one wavelength at one time. it consists of the entrance & exit slits, dispersing element (like grating) &mirror. it detects the light and measure the intensities with a photomultiplier tube or other detectors and data acquisition system. spectrograph also gives the spectrum of all intensities of a wavelength at one time.it consists of the entrance & exit slits, dispersing element (like grating) &mirror but it does not have any detector and does not record the spectrum.
What are two ways that an object gives of light?
A torch emits light from the bulb. A mirror gives off light by reflection.
Does a light bulb give off radiant or thermal energy?
THe light bulb emits light while in the process heat in the infrared spectrum is emitted.

Light at 489 nanometers is in the blue area of the spectrum. Use the link below for more information.
What is the difference between an absorption and an emission spectrum?
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
What are the different color spectra of a LED?
A single LED emits light at one single frequency, so it has no spectrum.
What does it mean when something gives out of light?
Assuming that you mean light in the visible spectrum, it would mean that the thing is giving of radiation that is in the visible light spectrum
If you mix all the colored lights of the spectrum together they will appear?
White or sunlight -- the sun emits light very close to your description. =====================================
