Bright lines in the pattern show:
Correct answer: B. Emission
- A. Absorption
- B. Emission
- C. Release
- D. Free particle
Explanation
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from the emission or absorption of light of a particular frequency/wavelength. A bright line in the pattern shows the emission line spectra. It occurs when a hot gas emits radiation of a particular wavelength/frequency.

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.
