An electron in hydrogen atom is in the n=4 energy level. When it makes a transition to some lower energy level, to which series the wavelength of emitted photon belong?

Assertion: The electron in the hydrogen atom passes from energy level n = 4 to the n = 1 level. The maximum and minimum number of photon that can be emitted are six and one respectively. Reason: The photons are emitted when electron make a transtition from the higher energy state to the lower energy state.
