There are two ways to solve this :
1.Use the rydbergs equation to solve this question
                              OR
2.Calculate the energy difference between the two orbits and equate it hc/L  , where L is wavelength 
and subsequently you can calculate the value of L.
 
P.S-Actually both the methods are same but in the first one we use direct formula.
