$X$ different wavelength may be observed in the spectrum from a hydrogen sample if the atoms are excited to states with principal quantum number $n = 6$ ? The value of $X$ is

Answer:

15.00

Solution:

Use the concept of hydrogen like atom spectrum when the atoms are excited to a sixth excited state, to find different wavelengths observed in the spectrum. The total possible transitions are,

$\frac{n ( n - 1 )}{2} = \frac{6 \times 5}{2} = 15$

Here $n$ is the principal quantum number.
