Analyzing +4 | -1

For given transitions order of wavelength of photon emitted will be :-

(A)

6 \rightarrow 4

(B)

4 \rightarrow 2

(C)

3 \rightarrow 1

(D)

2 \rightarrow 1

View answer and explanation

Correct option: B

\lambda_{\mathrm{C}}<\lambda_{\mathrm{D}}<\lambda_{\mathrm{B}}<\lambda_{\mathrm{A}}

Option A (

\lambda_{\mathrm{C}}>\lambda_{\mathrm{D}}>\lambda_{\mathrm{B}}>\lambda_{\mathrm{A}}

) is correct because the wavelength is inversely proportional to the energy difference between the levels, and the energy differences follow the order C < D < B < A.
