There are actually a lot more than 4, but those are the most prominent ones (or the ones four transitions for visible light n= within the visible spectrum or something, I would need to mug up on the four transitions for visible light n= details). Now let&39;s see if we can calculate the wavelength of light that&39;s emitted. The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). In that case the negative energy means a photon (of positive. 6 eV) 1/n f 2 - 1/n i 2. Put the visible light colors in order from longest wavelength to shortest wavelength. n = 7 and the emission is 397 nanometers (Violet Light verging on Near UltraViolet Light) Four of the wavelengths of the Balmer series occur in the visible spectrum (656 nm, 486 nm, 434 nm, and 410 nm). So let&39;s look at a visual representation of this.
This means that the photon is emitted and that interpretation was the original application of four transitions for visible light n= Rydberg. Essentially, that equates to the colors the human eye can see. Choice 3 has an increase in energy level, but the electron.
