Energy levels A, B and C of a certain atom correspond to increasing values of energy, i.e., EA< EB< EC. If l1, l2 and l3 are wavelengths corresponding to transitions C to B, B to A and C to A respectively then –
A
l3 = l1 + l2
B
l3 = λ1+λ2λ1λ2
C
l1 + l2 + l3 = 0
D
l32 = l12+ l22
Answer
l3 = λ1+λ2λ1λ2
Explanation
Solution
EC – EA = EC – EB + EB – EAŽλ3hc= λ1hc + λ2hc
