==Write an example question showing the calculation of the frequency of EM radiation required to excite an H atom from ground to n=2 electronic state.==
The energy of the hydrogen atom is calculated using the following equation:
'''Energy of Hydrogen Atom''' : 6 1 black white
To calculate the change in energy required to go from the ground state to n=2, the following equation is used:
δE =((9.10938x10)−31kg(1.60218x10−19c)432π28.854x1012c2S2/kgm2)2(1.054x10−24J.s)2)54
