Answer 2

Answer:

Emission spectrum is given by elements in all of their phases, which are basically solid, liquid and gaseous. Therefore, the correct option would be d) all of the above.

Explanation:

When an atom or molecule absorbs energy, the electrons are excited to a better energy level. When the electron falls again to the decrease energy level, light is emitted, which has the energy equal to the better and the decrease states’ energy difference. Due to the supply of a couple of states of energy, an electron can go through several transitions, every giving upward thrust to a completely unique wavelength that incorporates the emission spectrum.

When electromagnetic radiation passes through a material, part of the electromagnetic radiation can be absorbed. In that case, while the final radiation is surpassed through a prism, a spectrum is acquired with an opening in it, known as an absorption spectrum. The absorption spectrum is feature of a selected detail or compound and does now no longer extrade with various concentrations.
