explain the hydrogen spectrum on the basis of Bohr\'s atomic theory

1.	explain the hydrogen spectrum on the basis of Bohr\'s atomic theory
Answer» According to Bohr,\tWhen energy is supplied to atoms of hydrogen, the electron from lower energy gets excited to higher energy level.\tThe excited state being unstable, it jumps back to its original state that is ground state.\tSome electrons move to their ground state in one jump, some in multiple jumps. Each jump corresponds to line in a spectrum.\tAs we know the gas in tube consists of many hydrogen atoms.\tTherefore, each electron on getting energy gets excited.\tOn returning to the ground state, they either move in single jump or multiple jump.\tThis is the reason that we get so many lines in different regions in hydrogen spectrum.The wavelength emitted by them can be calculated as:
