एक हाइड्रोजन परमाणु इलेक्ट्रॉन \(( n +1)^{ th }\) कक्षा से \(n ^{\text {th }}\) कक्षा पर जाता है। यदि \(n>>1\) हो तो उत्सर्जित विकिरण की आवृत्ति निम्न में से किसके समानुपाती होगी?

  1. A \(\frac{1}{n^{4}}\)
  2. B \(\frac{1}{n^{3}}\)
  3. C \(\frac{1}{n^{2}}\)
  4. D \(\frac{1}{n}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{1}{n^{3}}\)

Step-by-step Solution

Detailed explanation

In hydrogen atom, \(E _{ n }=\frac{- E _{0}}{ n ^{2}}\) Where \(E _{0}\) is Ionisation Energy of \(H\). \(\rightarrow\) For transition from \((n+1)\) to \(n,\) the energy of emitted radiation is equal to the difference in energies of levels. \(\Delta E = E _{ n +1}- E _{ n }\)…
