What type of spectrum is produced when elements are heated?

Visible
Radio
Ultraviolet
Infrared

The correct answer is: Infrared

When elements are heated, they emit radiation in the form of a continuous spectrum of light, including all wavelengths from visible light to infrared light. While visible light is a type of spectrum produced by light sources such as the sun or light bulbs, it is not specifically produced when elements are heated. Radio and ultraviolet spectra are also produced by certain sources, but they are not the type of spectrum produced when elements are heated. Therefore, the correct answer is D, infrared.
