Here we plug that in so were going to plug in -2.18 x 10^-18 joules/atoms and thatd just be 4 squared which is 16. The emission lines correspond to photons of discrete energies that are emitted when excited atomic states in the gas make transitions back to lower-lying levels. Another fundamental discovery in the history of mankind was the invention of the printing press. As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa. The de Broglie wavelength formula allows us to calculate the de Broglie wavelength of the electron if we know its momentum. Electron Transition: Electron transition occurs when an electron changes from one energy level to another. c=v Further rearranging the equation, =c/v or, v=c/ The above equations indicate that wavelength and frequency are inversely related to each other. The research of spectra as an indicator of the state of a system turned out to be extremely useful. Were going to use the Balmer Equation which relates wavelengths to a photons electronic transitions.   To solve for the wavelength, start by simplifying on the right side of the equation. How do you find the wavelength of light in quantum mechanics? These isotopes were the first of the 213 isotopes of various atoms that he later discovered.
