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.
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.
The sun emits a continuous spectrum, which includes all wavelengths of light across the electromagnetic spectrum. This spectrum results from the thermal radiation of the sun's surface.
The photosphere emits the visible light from the sun.
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.
A prism or a diffraction grating can be used to split light into a spectrum for analysis. These devices work by dispersing light into its component colors based on their different wavelengths. This allows for the analysis of the composition of light or materials based on the patterns observed in the resulting spectrum.

The spectrum is a kind of analysis of the light emitted by a star.

THe light bulb emits light while in the process heat in the infrared spectrum is emitted.
A lightbulb primarily produces a continuous spectrum rather than a discrete spectrum. This is because it emits light through thermal radiation, where the filament heats up and emits a broad range of wavelengths. In contrast, a discrete spectrum is characteristic of gases or certain materials that emit light at specific wavelengths due to electronic transitions. Therefore, while a lightbulb emits a continuous spectrum, it does not produce a discrete spectrum.
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.
The spectrum of light from a star appears continuous, without gaps, because it is a result of the superposition of light emitted at different wavelengths. This continuous spectrum is produced as the star emits light across a range of wavelengths leading to a smooth distribution of colors in the spectrum.
The sun emits a continuous spectrum, which includes all wavelengths of light across the electromagnetic spectrum. This spectrum results from the thermal radiation of the sun's surface.
A torch emits light from the bulb. A mirror gives off light by reflection.
