A) 6
B) 7
C) 8
D) 9
Correct Answer: A
Solution :
Number of possible emission lines are \[n(n-1)/2\] When electron jumps from \[nth\] state to ground state. For this question, this value should be\[\frac{(n-1)(n-2)}{2}\] Hence, \[\frac{(n-1)(n-2)}{2}=10\] Solving we get n = 6. Hence, the correction option is (a).You need to login to perform this action.
