MCQ
Spectrum of sunlight is an example for:
  • A
    Band emission spectrum
  • ✓
    Line absorption spectrum
  • C
    Continuous emission spectrum
  • D
    Continuous absorption spectrum
✓

Answer

Correct option: B.
Line absorption spectrum

Dark/ Bright light seen in an otherwise uniform and continous spectrum is a spectral line, this is due to emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
Spectrum of sunlight is an example for line absorption spectrum.
