The electron in hydrogen atom is initially in the third excited state. When it finally moves to ground state, the maximum number of spectral lines emitted are

Options:

Answer:

Solution:

Initially the electron is in the third excited state i.e., $n = 4$ Hence maximum number of spectral lines emitted $= \frac{n ( n - 1 )}{2} = \frac{4 ( 4 - 1 )}{2} = 6$
