Question: The order of energies of energy levels A, B and C is E<sub>A</sub>\< E<sub>B</sub>\< E<sub>C</sub>. ...
The order of energies of energy levels A, B and C is EA< EB< EC. If the wavelength corresponding to transition C ® B, B ® A and C ® A are l1, l2 and l3 respectively, then which of the following relation is correct?
A
l1 + l2 + l3 = 0
B
l32 = l12 + l22
C
l3 = l1 + l2
D
l3 = λ1+λ2λ1λ2
Answer
l3 = λ1+λ2λ1λ2
Explanation
Solution
ECA = ECB + EBA
λ31= λ1λ2λ1+λ2
\ l3 = λ1+λ2λ1λ2
