(a)
Interpretation: The
Concept Introduction: When transition of electrons happens, there is a certain amount of change in energy levels, associated with it, and this provides more information about the molecular structure and its properties.
(b)
Interpretation: The
Concept Introduction: The magnitude of photoelectric current increases when there is an increase in the intensity of incident radiation.
(c)
Interpretation: The Conjugated
Concept Introduction: A conjugated system generally decreases the energy level of a molecule, thus increasing its stability.
(d)
Interpretation: The Chromophore needs to be defined.
Concept Introduction: Chromophore is a group of chemicals, that provides color for a molecule by way of absorption of light at a particular frequency.
(e)
Interpretation: The Visible Spectrum needs to be defined.
Concept Introduction: The visible spectrum helps in the study of the universe and earth.
(f)
Interpretation: The Cut-Off point of a solvent needs to be defined.
Concept Introduction: All light is absorbed by the solvent, below the cut-off point of the solvent.
(g)
Interpretation: The Electronic transition needs to be defined.
Concept Introduction: When the energy of an electron gets transferred from one energy level to another energy level, then it is called electronic transition.
(h)
Interpretation: The absorbance needs to be defined.
Concept Introduction: The light absorbing capacity of a substance is called absorbance. The incident light has a specified wave length.
