Q1

Energy levels A, B and C of an atom correspond to increasing values of energy i.e. \({\mathrm{E}}_{\mathrm{A}}<{\mathrm{E}}_{\mathrm{B}}<{\mathrm{E}}_{\mathrm{C}}\). Let \({\lambda }_{1},{\lambda }_{2}\) and \({\lambda }_{3}\) be the wavelengths of radiation corresponding to the transitions C to \(\mathrm{B}, \mathrm{B}\) to A and C to A , respectively. The correct relation between \({\lambda }_{1},{\lambda }_{2}\) and \({\lambda }_{3}\) is :

a

\({\lambda }_{1}^{2}+{\lambda }_{2}^{2}={\lambda }_{3}^{2}\)

b

\(\frac{1}{{\lambda }_{1}}+\frac{1}{{\lambda }_{2}}=\frac{1}{{\lambda }_{3}}\)

c

\({\lambda }_{1}+{\lambda }_{2}+{\lambda }_{3}=0\)

d

\({\lambda }_{1}+{\lambda }_{2}={\lambda }_{3}\)
