A laser is a device that produces a thin stream of light of just a few close wavelengths.
A device that breaks light into colors and produces an image is a spectrophotometer or a spectrometer. These instruments measure the intensity of light as a function of its color or wavelength.
A typical incandescent light bulb produces light by heating a filament wire until it glows. The glowing filament produces both visible light and heat.
A device that produces light of only one color is called a monochromatic light source. This can be achieved using devices like lasers, LEDs (Light Emitting Diodes), or filters to isolate a specific wavelength of light.

An example of an electric device that produces light is a light bulb. When electricity is passed through the filament inside the bulb, it heats up and emits light.
An example of a device that can transform electrical energy into light, heat, and sound is a typical household incandescent light bulb. When electricity flows through the filament of the bulb, it generates light by producing heat, and also produces sound in the form of a faint humming noise due to the vibration of the filament.
Light: lightbulbs, television sets, computer screens, indicator LEDs on different devices, a stove (the one that has an open flame). Heat: All of the above. Besides, just about any device that uses electricity will produce waste heat; for example a refrigerator, a computer, a radio, etc. Also, some devices are specifically designed to produce heat - such as the stove, a heater, or a hair drier.
No, a device that breaks light into colors and produces an image of the spectrum is called a spectroscope. The electromagnetic spectrum refers to the range of all possible frequencies of electromagnetic radiation.
