If change in energy (ΔE) = 3x 10 -8 j, h= 6.64x 10 -34 j-s and c= 3x 10 8 m/s then wavelength of the light is: (1) 6.36x 10 3 Å (2) 6.36x 10 5 Å
The energy of second Bohr orbit of the hydrogen atom is -328 kJ mol-1, hence the energy of fourth Bohr orbit would be: (1) - 41 kJ mol -1 (2) -1312 kJ mol -1 (3) -164
