Question

Question

1) Calculate the energy change corresponding to the excitation of an electron from the n=1 to n=3 electronic state in the hydrogen atom.

2) Calculate the wavelength of electromagnetic radiation associated with the energy change above.

Answer 1

Answer #1

As we know

E = hcR*(1/n1^2 - 1/n2^2)

= (6.626*10^-34*3*10^8*10973731.6)*(1 - 1/9)

= 1.9389*10^-18 J

Wavelength = hc/Energy

= (6.626*10^-34*3*10^8)/(1.9389*10^-18)

= 1.025*10^-7 m
