Im confused on how to start this problem, guidance will be much appreciated.

Give: 211nm n=1 --> 5

          306nm n=1 -->3

         422nm n=2 -->4

          348nm n=???

          1988nm n=??

          716nm n=??

and so on... then find the energy of each energy level. So n=1 Energy = 0                                                                      

So n=1 Energy = 0

      n=2 energy = ???

All the way up to n=5. Do I use Change in E= -(HCR)/n^2 ?

Solution

the formula is E2-E1= hc/wavelength

use this formula to get the answers

for ex. as E1=0 therefore from 1st value E5= hc/211nm
