The figure shows electronic wave function for a hydrogen atom.

Answer»

The quantum number of this STATE is 6
The wavelength of this electron is `6pir_(0)` (r_(0) is RADIUS of ground state)
It can go to ground state by emitting 3 different photons
On deexcitation it emits at least one line in infra red REGION of spectrum.

Solution :(A) `n=3`
(B) `2pir=nlambda Rightarrow 2pi3^(2)r_(0)=nlambda Rightarrow lambda=6pir_(0)`
(C) No `=^(3)C_(2)=3`
(D) all lines in Balmer or lyman SERIES.
