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

Question

TestHub · Accepted Answer

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.
