Spectra corresponding to sodium vapour lap is:
Correct answer: C. Emission spectra
- A. Band spectra
- B. Line spectra
- C. Emission spectra
- D. Absorption spectra
Explanation
Option A : Spectra corresponding to sodium vapour lamp is not band spectra.Option B : Spectra corresponding to sodium vapour lamp is not line spectra.Option: CA sodium lamp gives an emission spectrum having two yellow lines.The predominant yellow line in the spectrum of a sodium vapour lamp has a wavelength of 590nm.Option D : Spectra corresponding to sodium vapour lamp is not absorption spectra. It is emission spectra.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
