Continuous adsorption spectrum is obtained from:
Correct answer: A. excited atoms
- A. excited atoms
- B. Excited molecules
- C. Ground state molecules
- D. Ground state atoms
Explanation
Excited atoms: When atoms are excited, either by heating or by other means such as electrical discharge, they absorb energy and transition to higher energy levels. As these excited atoms return to their ground state, they emit energy in the form of electromagnetic radiation. The absorption and emission of specific wavelengths of light result in a continuous adsorption spectrum. In summary, a continuous adsorption spectrum is obtained from excited atoms, where the absorption of energy and subsequent emission of light results in a continuous range of wavelengths.

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
