Which is / are correct statement.
(A) The difference in angular momentum associated with the electron present in consecutive orbits of
\( P \)
\( \mathrm{H} \)-atom is \( (\mathrm{n}-1) \frac{\mathrm{h}}{2 \pi} \)
W
(B) Energy difference between energy levels will be changed if, P.E. at infinity assigned value other than zero.
(C) Frequency of spectral line in a \( \mathrm{H} \)-atom is in the order of \( (2 \rightarrow 1)(3 \rightarrow 1)(4 \rightarrow 1) \)
(D) On moving away from the nucleus, kinetic energy of electron decreases.
(1) A, B
