Energy levels A, B and C of a certain atom corresponding to increasing values of energy i.e., E_{A} < E_{B} < E_{C}. If \\lambda_{1}, \\lambda_{2} and \\lambda_{3} are wavelengths of radiations corresponding to transitions C to B, B to A and C to A respectively, which of the following relations is correct? (2005, 1990)

Correct Answer is : λ3=λ1λ2λ1+λ2

\\lambda_{3}=\\lambda_{1}+\\lambda_{2}

\\lambda_{3}= {\\lambda_{1} \\lambda_{2}}/{\\lambda_{1}+\\lambda_{2}}

\\lambda_{1}+\\lambda_{2}+\\lambda_{3}=0

\\lambda_{3}{ }^{2}=\\lambda_{1}{ }^{2}+\\lambda_{2}{ }^{2}

Energy levels A,B and C of a certain atom corresponding to increasing values of energy i.e., EA<EB<EC. If λ1,λ2 and λ3 are wavelengths of radiations corresponding to transitions C to B,B to A and C to A respectively, which of the following relations is correct?

(2005, 1990)

λ3=λ1+λ2
λ3=
λ1λ2
λ1+λ2
λ1+λ2+λ3=0
λ3‌2=λ1‌2+λ2‌2
