Using Bohr's postulates, derive the expression for the total energy of the electron revolving in n^(th) orbit of hydrogen atom. Find the wavelength of H_(alpha) line, given the value of Rydberg constant, R = 1.1 xx 10^(7) m^(1)

Write Bohr's any two postulates for hydrogen atom.

On the basis of Bohr.s theory, derive an expression for the radius of the n^(th) orbit of an electron of hydrogen atom.

A particle known as mu meson has a charge equal to that of no electron and mass 208 times the mass of the electron B moves in a circular orbit around a nucleus of charge +3e Take the mass of the nucleus to be infinite Assuming that the bohr's model is applicable to this system (a)drive an expression for the radius of the nth Bohr orbit (b) find the value of a for which the radius of the orbit it appropriately the same as that at the first bohr for a hydrogen atom (c) find the wavelength of the radiation emitted when the u - mean jump from the orbit to the first orbit
