An electron in hydrogen atom in the level n = 5 undergoes atransition to level n = 2:
Given: RH = 1.09 X 10 7 m-1 h = 6.627 X 10-34 J. s. C = 2.99 X 10 8 m/s
Mass of electron = me = 9.11 X 10 -31 kg J = kg m2 / s2
A: What would be the region of spectrum for electromagnetic radiation?
B: Find the speed of this electron?
