As telephony and electrical engineering developed, various scrambling methods to code the acoustic signals based on mathematical algorithms were being used, to make it more difficult to steal the information transmitted in this manner. Electrons can only occupy specific energy levels in an atom. As we have already discussed earlier, emission spectra are primarily characterized by the transition of the electrons in the outer shells of the atom. Bohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. #1/(lamda) = R * (1/n_(final)^(2) 1/n_(initial)^(2))#, where.
