Solution

The correct option is D λR(λR1)
we know that, 1λ=RZ2(1n2L1n2H)

The hydrogen atom returns to the ground state

n2L=1 and Z for hydrogen atom=1
Substituting in the equation, we get

1λ=RZ2(1121n2H)

1λ=R.1.(11n2)

1λ=R(11n2)

1λR=R(11n2)

1λR=11n2

1n2=11λR

1n2=λR1λR

n=λRλR1

So, the correct option is B
