Find the wavelength of the balmer series spectral line corresponding to n = 12.

The wavelength of the Balmer series spectral line corresponding to n = 12 is 375 nm.

Explanation:

let λ be the wavelrngth of the spectral line.

let ni be the initial energy state, for Balmer series, ni = 4.

let nf be the final energy level, n = 12.

Balmer series states the following:

1/λ = R[1/(ni)^2 - 1/(nf^2))

λ = 1/[R[1/(ni)^2 - 1/(nf^2))]

  = 1/[(1.09737×10^7)×[1/(4)^2 - 1/(12^2))]

  = 375 nm

Therefore, the wavelength of the Balmer series spectral line corresponding to n = 12 is 375 nm.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
