The radiations emitted from hydrogen filled discharge tube shows:
Correct answer: C. Line spectrum
- A. Continuous spectrum
- B. Band spectrum
- C. Line spectrum
- D. None of these
Explanation
When the radiations emitted from a hydrogen-filled discharge tube are passed through a prism or a diffraction grating, they produce a series of discrete and well-defined lines on the spectrum. Each line corresponds to a specific wavelength of light, indicating that only certain energy levels are allowed in the hydrogen atom. This is a characteristic feature of atomic emission spectra, and it occurs when electrons in the atom transition between different energy levels.

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.
