Neils Bohr was the first to explain quantitatively the general features of hydrogen atom structure and its spectrum. Calculate the wave number of radiation due to transition of an electron from fourth orbit to second orbit `(R_h=109677cm^-1)`

Neils Bohr was the first to explain quantitatively the general features of hydrogen atom structure and its spectrum. a) Give the main postulates of Bohr's model.

Neils Bohr was the first to explain quantitatively the general features of hydrogen atom structure and its spectrum. b) Find the maximum number of emission lines, when the excited electron of hydrogen atom in n=6, drops to the ground state (n=1).

Bohr was the first to explain the structure of hydrogen atom and spectrum. Calculate the wavelength of the first line in the Lyman series of the hydrogen spectrum. ( R= 109677 cm^(-1))

The Balmer series of lines in the hydrogen spectrum appear in the visible region of the electron magnetic spectrum . Calculate the wave number of the second line in the Balmer series. ( Rydberg constant for hydrogen is 109677 cm^(-1)
