Spectral Lines in Hydrogen Spectrum

The hydrogen spectrum refers to the series of spectral lines that are produced when electrons in a hydrogen atom move from higher to lower energy levels. These transitions result in the emission of electromagnetic radiation, which can be detected and analyzed using spectroscopy.

Number of Spectral Lines

The number of spectral lines in the hydrogen spectrum depends on the number of energy levels that the electrons can occupy. In the case of hydrogen, there are an infinite number of energy levels, but only a finite number of these levels are accessible to the electrons.

The spectral lines that are produced in the hydrogen spectrum correspond to transitions between these accessible energy levels. Each transition corresponds to a specific wavelength of electromagnetic radiation, which can be detected as a spectral line.

Therefore, the correct answer to the question is option C, multiple. There are multiple spectral lines in the hydrogen spectrum, corresponding to the various transitions between energy levels.

Conclusion

In summary, the hydrogen spectrum is characterized by multiple spectral lines that correspond to transitions between energy levels in the atom. The number of spectral lines is finite but large, and each line corresponds to a specific wavelength of electromagnetic radiation. Understanding the hydrogen spectrum is important for a variety of scientific applications, including astronomy, chemistry, and physics.
