Question

If 9.9 eV energy is supplied to H atom, the no. of spectral lines emitted is equal to (1)0 (2)1 (3)2 (4)3

Answer 1

Answer:0

Explanation:Acc to ques energy given to H atom is 9.9ev. Let’s first calculate energy required to make lowest emmision possible which will be from orbit 2nd to orbit 1st so energy diff b/w them will be....13.6(1-1/4) which comes out to be 10.2....since energy given to H atom acc to ques is less as compared to enrgy required to make lowest emmision possible hence no emmision can take place...so answer will be (a) i.e 0
