The frequency of radiations emitted when electron falls from n = 4, to n = 1, in H-atom would be:
(Given E1 for H=2.18×10-18 J atom -1 and h=6.625 ×10-34 Js.)
1.54×1015 s-1
1.03×1015 s-1
3.08×1015 s-1
2.0×1015 s-1
The frequency of radiation emitted when the electron falls from n = 4 to n = 1 in a hydrogen atom will be
(Given ionization energy of H = 2.18 × 10−18 J atom−1 and h = 6.625 × 10−34Js)
