Give spectrum of Hydrogen atom and discuss its lines.

When an electron jumps from a higher energy level (n₂) to a lower energy level (n₁), energy is emitted in the form of radiation equal to the difference in energies: $$E2 - E1 = h\nu$$ From Bohr's theory, the total energy of an electron in the n-th orbit is: $$En = -\frac{me^4}{8\varepsilon0^2 n^2...
