Calculate the wavelength in nm of the line with n = 6 in the Pfund series of the spectrum of atomic hydrogen.

Answer 1

Use the following formula:

Wavenumber = R_H*((1/n1^2) - (1/n2)^2)

Where wavenumber = (1/wavelength),
R_H = Rydberg's constant,
n1 = The number corresponding to the series (Pfund = 5)
n2 = The 'n' value of the line (n = 6)
