What type of spectrum does an incandescent light bulb produce?

An incandescent light bulb produces a continuous spectrum of light, which includes a wide range of wavelengths across the visible spectrum, as well as infrared and some ultraviolet light. This type of spectrum is characterized by smooth transitions between colors, lacking distinct lines or bands. The light is primarily generated by heating a metal filament, typically tungsten, until it glows, emitting light across a broad range of wavelengths. As a result, the light appears warm and has a yellowish hue.
