Explanation:
Physicist Rydberg generalized for hydrogen the reciprocal of emission spectrum wavelengths (in a vacuum)
1/lambda_"vac" = R_"H" * (1/n_"lower" - 1/n_"upper")
where
R_"H" = 1/(912 xx 10^(-10) color(white)(l) "m")
For this particular transition
n_"upper" = 4 n_"lower" = 3
Thus
1/lambda_"vac" = 1/(912 xx 10^(-10) color(white)(l) "m") * (1/(3^2) - 1/(4^2))
color(white)(1/lambda_"vac") ~~ 1.88 xx 10^(-6) color(white)(l) "m"
