Question

In terms of the Rydberg’s constant R, the minimum wavelength in the Lyman series is  

Solution

Correct option is

Wavelength  in Lyman series is given by 

         

Since Z = 1 (for hydrogen) then for hydrogen  

          

Thus, the minimum  corresponds to . Therefore,    

       .
