A lamp filament is made of tungsten. Why do we get a continuous spectrum rather than a tungsten line spectrum when light from an incandescent lamp is viewed with a spectroscope?
The tungsten filament emits white light, or the entire spectrum of colors of light. (look at any light bulb when its on). When the light is viewed with a spectroscope, it separates the white light into the different colors.
