When an atom absorbs energy the lines in the spectrum will appear which are_________________?
Correct answer: B. Darker
- A. Brighter
- B. Darker
- C. Colourless
- D. Hard to locate
Explanation
When atoms absorb selected frequencies of energy, electrons move to higher energy levels and remove those wavelengths from transmitted light, producing dark absorption lines. Bright lines are produced when excited electrons emit energy while returning to lower levels. Students may choose a by confusing absorption with emission spectra.

About Spectrum of Hydrogen
The hydrogen spectrum consists of discrete emission lines produced when electrons fall between quantised energy levels and release photons. Questions use the Rydberg equation, photon energy and wavelength, and identify the Lyman, Balmer, Paschen, Brackett and Pfund series, which differ from continuous spectra.
