Concept explainers
Interpretation: The wavelength required to break the given molecule with given
Concept Introduction:
Bond Dissociation Energy: The minimum energy required to break a bond between two atoms present in the molecule is called bond dissociation energy.
Energy: The energy is conversed property since it can neither be created nor be destroyed but can be transformed. The energy of the photon is obtained by using the following relation
Wavelength: The distance between the two continuous maximum displacements present in wave or the two continuous minimum displacements present in a wave exhibited by the photons is called wavelength. The wavelength of the photon is inversely proportional to its frequency. The relationship between them is given by the following formula,
Frequency: It denotes the number of waves passes in given amount of time.
