Correct answer: B. 10-3s
- A. 10-8s
- B. 10-3s
- C. 10-10s
- D. 10-6s
Explanation
Meta stable state is the state in which electrons stay for a longer duration (about10-3).

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.
