Incorrect statement: In the emission spectrum, transition takes place with the absorption of a photon of energy hv.
Explanation:
The emission spectrum is a set of wavelengths of electromagnetic radiation emitted by an atom when its electrons transition from higher energy levels (excited state) to lower energy levels (ground state). The emission spectrum is a characteristic property of each element and can be used to identify the presence of specific elements.
Statement (a): Emission spectrum results when an electron in an atom undergoes a transition from an excited state to the ground state.
This statement is correct. When an electron in an atom jumps from a higher energy state to a lower energy state, it emits a photon of specific energy, resulting in the emission spectrum.
Statement (b): In the emission spectrum, transition takes place with the emission of a photon of energy hv.
This statement is correct. In the emission spectrum, the transition of an electron from a higher energy level to a lower energy level results in the emission of a photon of specific energy. The energy of the emitted photon is given by the equation E = hv, where E is the energy of the photon, h is Planck's constant, and v is the frequency of the photon.
Statement (c): In the emission spectrum, transition takes place with the absorption of a photon of energy hv.
This statement is incorrect. In the emission spectrum, the transition of an electron occurs with the emission, not absorption, of a photon. When an electron drops from a higher energy level to a lower energy level, it releases energy in the form of a photon.
Therefore, the incorrect statement is option (c). The emission spectrum is characterized by the emission of photons, not the absorption of photons.
