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

Correct answer

0

Step-by-step 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, n n - 1 2 = 6 × 5 2 = 15 Here n is the principal quantum number.
