For my homework, there are two parts to the question. i did part a and I got
E= 6.54E18J.
Part A) Calculate the energy (in J) of the photon associated with the transition of the electron in He from n=2 to n=1.
Part B) As the Vaule of Z increases, does the wavelength of the photon associated with the transition from n=2 to n=1 increase or decrease?
Please show me the steps or give me some helpful information so, I can learn how to do it on my own.
