Question

Maximum numbers pf spectral lines emitted when an electron jumps from n=5to n=1 in hydrogen atom is

Answer 1

Answer:

10

Explanation:

No. of spectral lines: (n2-n1) (n2-n1+1)/2

n is shell no.

Answer 2

Answer:No of spectral lines emitted are summation of difference of N2 andN1

Explanation:

N2=5,,N1=1,,it means is fall in Lyman series line

Difference between them is 4,,

Summation of difference=4+3+2+1=10 spectral lines emitted

4 in Lyman series (Uv region),,3inBalmer series (visible region),,

2inpaschann region (near IR region)

1in Bracket region (middle IR region)

0 in pfund region (far IR region)
