Question

Assertion :In a hydrogen atom, energy of emitted photon corresponding to transition from $n=2$ to $n=1$ is much greater as compared to transition from $n=\infty$ to $n=2$ Reason: Wavelength of photon is directly proportional to the energy of emitted photon

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

Energy of $n=1$ is $-13.6eV,n=2$ is $-3.4eV$, infinite orbit is considred to have zero energy.
Therefore, $E_2-E_1>E_{\infty }-E_2$
But, wavelength is not directly proportional to $n$.
Therefore, assertion is correct but reason is wrong.
