MCQ
An atom has $x$ energy level, then total number of lines in its spectrum are
- A$1 + 2 + 3 +----------+ (x + 1)$
- B$1 + 2 + 3 +----------+ x^2$
- ✓$1 + 2 + 3 +----------+ (x -1)$
- D$(x + 1) (x + 2) (x + 4)$
✓
Answer
Correct option: C.
$1 + 2 + 3 +----------+ (x -1)$
c
No. of spectral lines $= (x -1) + (x -2) + (x -3) + .... +3 + 2 + 1$
No. of spectral lines $= (x -1) + (x -2) + (x -3) + .... +3 + 2 + 1$
