Thank you for the opportunity to help you with your question!

answer is 

 4.86 x 10-7  m.............................answer

= 486 nm..............................................answer



1 /  λ  = R ( (1 / n1^2 )- (1/ n2^2 ) )

 1 /  λ  =  1.0974x107 ( (1 /2^2 )- (1/ 4^2 ) )

            = 1.0974x10^7 ( (1 / 4 )- (1/ 16 ) )

             = 0.2057625 * 10^7

 λ =  1/   0.2057625 * 10^7

   = 4.859972055 * 10^ -7

  = 4.86 x 10-7  m .....................................................ANSWER

  =  486  nm.....................................ANSWER
