[Chem] Calculation

我唔太識點形容呢條問題係歸納去邊類,所以叫左佢做calculation先:icon101:
The electron residing in the 2px orbital of an electronically excited hydrogen atom is promoted to the 4dxy orbital by absorption of a photon of laser light. The shortest wavelength of light that can be emitted by the resulting electroncially exictied hydrogren atom is:
A. Cannot be determined
B. 9700 nm
C. 97nm
D. 97 x 10^10 m
E. 485nm
正確答案係C.97nm
但我計黎計去都係485nm:icon101:
求高人指點
