Red Orange Yellow Green Blue Violet Color of Line Noted Red Orange Yellow Green Blue Violet Emission Spectrum of Sunlight Color of Line Noted Wavelength (nanometers) Red 580-620 Orange 570-590 Green 490-570 Blue 410-460 Treatment of Data Calculation of Hydrogen Energies: Energy = (hc)/ λ where h is Plank’s constant (6.626 x 10 -34 Js), c is the velocity of light (2.998 x 10 8 m/s), and λ is the wavelength in meters. Therefore, the calculations of the hydrogen energies from the data are as follows:
Energy violet = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(410 nm) (1 m/ 10 9 nm)] = 4.845 x 10 -19 J Energy blue = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(430 nm) (1 m/ 10 9 nm)] = 4.620 x 10 -19 J Energy green = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(480 nm) (1 m/ 10 9 nm)] = 4.138 x 10 -19 J Energy red = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(650 nm) (1 m/ 10 9 nm)] = 3.056 x 10 -19 J The calculations of the hydrogen energies from the visible spectrum are as follows: Energy violet = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(410.2 nm) (1 m/ 10 9 nm)] = 4.843 x 10 -19 J Energy blue = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(434.1 nm) (1 m/ 10 9 nm)] = 4.576 x 10 -19 J Energy green = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(486.1 nm) (1 m/ 10 9 nm)] = 4.087 x 10 -19 J Energy red = [(6.626 x 10 -34 Js) (2.998 x 10 8 m/s)] / [(656.3 nm) (1 m/ 10 9 nm)] = 3.027 x 10 -19 J From the calculations, it is shown that the collected data is very similar to the actual data of the visible spectrum. Therefore, the energies obtained from the collected data are fairly accurate. Calculation of Initial Orbit Number: To calculate the initial orbit number, n initial, for the Bohr model of the hydrogen spectrum, the follow equation must be used: ΔE = 2.179 x 10 -18 [(1/n 2 final ) – (1/n 2 initial )] joules All of the lines of the hydrogen spectrum that lie in the visible region have a final orbit number of two. Therefore, n final can be interpreted as n final = 2. ΔE is the hydrogen energies in relation to the various colors. n inital of violet :

Therefore, the initial orbit number of violet is six because according to the Bohr model the value of the principal quantum number can only be integers between one and infinity. n
