Q2: I need to compare the observed lines to the ones that I calculate.
The observed, recorded wave length lines were:
RED = 650 nanometers
TURQUOISE = 490 nanometers
VIOLET 1 = 435 nanometers
VIOLET 2 = 405 nanometers
(The lines above were observed by looking at the line spectra from hydrogen gas being placed in an electrical discharge tube.)© BrainMass Inc. brainmass.com December 19, 2018, 11:46 pm ad1c9bdddf

Q: I need to calculate the visible lines that should be seen with a spectroscope.
A: Balmer Series is formed due electron transition from n ≥ 3 to n =2 orbits.
So the energy associated with this transition can be written as,
E = 13.6/22 - 13.6/n2] eV
E = [13.6/4 - 13.6/n2] * 1.6 x 10^-19 J
We also know the energy of a photon
E = hf = h c/ ...
This is a physics laboratory experiment. I have theoretically found the wavelength of spectral lines in Balmer series of Hydrogen. Then I have compared these values with the experimentally found values by finding the percent difference.
