- AA discrete series of lines of equal intensity and equally spaced with respect to wavelength equally.
- BA series of only four lines
- CA continuous emission of radiation of all frequencies
- DSeveral discrete series of lines with both intensity and spacings between lines decreasing as the wavenumber increases with each series.
The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom. These lines have decreasing spacings(as shown below)
This option is not correct. The emission spectrum of atomic hydrogen does not describe a discrete series of lines of equal intensity and equally spaced concerning wavelength equally.
This option is also incorrect. The emission spectrum also does not describe a series of only four lines.
This option is also incorrect. The emission spectrum of the hydrogen atom also does not describe a continuous emission of radiation of all frequencies.
The emission spectrum of atomic hydrogen has been divided into several spectral lines, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron-making transitions between two energy levels in an atom. These lines have decreasing spacings (as shown below):
