Question
An electron in hydrogen atom first jumps from second existed state to first excited state and then, from first excited state to ground state. Let the ratio of wavelength, momentum and energy of photons in the two cases be x,y and z, then select the wrong answer /(s)
Options
A.z = 1/x
B.x = 9/4
C.y = 5/27
D.z = 5/27
Solution
E1 = 
For second excited state to first excited state
E1 =
For first excited state to ground excited state
E2 =
(A)
(B) 
(C) P ∝
For second excited state to first excited state
E1 =
For first excited state to ground excited state
E2 =
(A)
(B) (C) P ∝
