If you replace mercury light with sodium vapour lamp in spectrometer experiment what colors do you observe in the spectrum?

Answer 1

Green, Yellow and Orange.

Answer 2

If you replace a Mercury light with a sodium vapor lamp in a spectrometer experiment, you would observe only a few specific colors in the spectrum. These colors would correspond to the characteristic emission lines of sodium, such as the bright yellow spectral lines at 589.0 nm and 589.6 nm. Sodium vapor lamps emit light predominantly in the yellow region of the spectrum.
