Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change. The theory of quantum mechanics, a set of mathematical rules that describe the behaviour of matter and its interactions, provides a good model for the description of atomic structure and properties.

In atomic physics, the Rutherford-Bohr model or Bohr model or Bohr model of the atom was first proposed by Niels Bohr in 1913. It was the first quantum theory of the atomic structure, applying the principles of quantum mechanics to the hydrogen atom. The Rutherford-Bohr model is a planetary model in which the electron is assumed to revolve around the nucleus in circular orbits. The Rutherford-Bohr model of the atom was based on Max Planck's quantum theory of radiation, which explained the spectrum of blackbody radiation, and Albert Einstein's theory of the photoelectric effect, which explained the origin of the spectrum of line emission from atoms. The Bohr model of the atom was the first to explain the discrete spectrum of hydrogen and how the spectral lines of the hydrogen atom were split into multiple spectral lines in a phenomenon called the fine structure. It introduced the Bohr radius and the concept of quantum levels to explain the discrete nature of the spectrum of the hydrogen atom. The Bohr model of the atom had a significant influence on the development of quantum mechanics, and was instrumental in the development and validation of quantum mechanics.

here. We want to calculate Weylandt off the bomber cities. Spectral line responding to an equal to 12. So we have here, um, equal toe 12. Expression for war. Expression for Weyland off any spectral cities is one a bomb Lambda is equal to are in doom one upon and primes minus one. A bomb. And so good. Farwell mysteries. He hell and Brian equal to two. Here are his boss Constant having well you off one fires, you know, 97 times attended a power seven about Amita. Nobody liking different values in the relation we have one upon Lambda is equal to 1.97 times. Attended a power seven. Burn me, Joe in tow one. A bomb to secure minus one. A bomb. Well, scared one upon island physical toe 1.97 times 10 to the power. So on. Pardon me. Gia in tow. Went upon for minus one of on one. 44. So from here we have the next stuff that it's one upon well and equal to 1.97 times tended a power seven. Pardon me, Joe. By making by taking the exam, we have a cynical toe. 1 44 here is 36 minus one. So we have one upon. Well, and is it Kal toh? 1.97 times 10 to the poor seven. Pardon me, Gia Indo 35 upon one 44. Nobody taking ISP local out the both fires at the Korean we have Linda equal to 1 44 upon 35 multiply one part 097 times tender. The Born seven Mitre. So we have Linda equal to two point 750 times Tended a power minus seven meter are we can ride it says Lemba equal to 3 75.0 Multiply dental power minus two. Much light into our minus seven. Our recon right judges 3 75 times tended a power minus nine meter and Linda equal to through 75. Tend to the bar minus nine is called Nano. We should you noted by And so we have Linda. That is a Maryland corresponding toe and musical to love in Balmer Series is she said you 3 75 nanometer their stance, sir. Thanks for watching
