Question

The wave number of electromagnetic radiation emitted during the transition of electron in between the levels of L+i on whose principal quantum numbers sum is 4 and difference is 2 is
1)3.5Rh 2) 4Rh 3) 8Rh 4)8÷9Rh ,whrere Rh is rydberg constant for hydrogen​

Answer 1

Answer:

8Rh

Explanation:

Since Wave number : Rh x Z square [1/n1^2 - 1/n2^2]

where z=3 (lithium atom)

solving n1 , n2 we get n1=1 and n2=3

substituting the values we get 8Rh
