Posted:

**Sun Oct 04, 2015 8:40 pm**this question states: "use the Rydberg formula for atomic hydrogen to calculate the wavelength of radiation generated by the transition from n=4 to n=2."

I am not sure why the answer I am getting is a number to the power of negative 19 when the answer in the book is 486 nm.

thanks
