Abstract Balmer Series of Hydrogen.-(1) A rigid comparison of experimental with theoretical results is the main purpose of the paper. It is concluded that Merton's measurements of the separation, half-width and relative intensity of the H α and H β doublets check with values derived from the recent Bohr-Kramers developments of the quantum theory, if a general field of volts per cm. is. How does quantum theory explain the line spectra of atoms? How does quantum theory explain the line spectra of atoms? a. The lines in the spectra arise from changes in the electron's wave function. b. The lines in the spectra arise from an electron rising to a higher subshell (that is, the value of l). c.

Niels Bohr and Albert Einstein. Selected works by Niels Søren Kierkegaard, Niels Bohr was born just around the corner from here, and feel like I should pay some kind of tribute to my deceased s, Niels Bohr is one of the most interesting theoretical physicists.
Bohr read Max Planck’s early quantum theory in and was instantly on the path to revolutionize the field. The objective of any theory claiming to explain an observed phenomenon is to provide a basis for arriving at the observed results/ measurements. So let us start with atomic emission spectra.
In the mid s, improvements in precision engineering. Quantum theory originated from experiments involving several aspects of electromagnetic energy and matter.
The study of blackbody radiation led to the idea of energy being quantized on an atomic level, which manifests itself in the line spectra of atoms. Ascribing a wave character to a moving particle led to the formulation of wave mechanics.
possibility is also of importance in the quantum theory of radiation. If a molecule absorbs or emits energy e in the form of radiation during its transition from one quantum-theoretically possible state to another, such an elementary process can be thought of as being partially or completely directional, or else symmetrical (non-directional).

Quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents— electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
These properties include the interactions of the particles with one another and with. The 20th century brought a major shift in our understanding of the atom, from the planetary model that Ernest Rutherford proposed to Niels Bohr’s application of quantum theory and waves to the behavior of electrons.
With a focus on Bohr’s work, the developments explored in this module were based on the advancements of many scientists over time and laid the groundwork for future scientists. Niels Bohr and Albert Einstein debating quantum theory at Paul Ehrenfest's home in Leiden (December ).
InNiels Bohr became a professor at the University of Copenhagen, and director of the newly constructed "Institute of Theoretical Physics" in Born: October 7,Copenhagen, Denmark.
In his paper , Bohr tried to extend his theory of line spectra to the then only recently discovered Stark effect () [ 21 ] and to the Zeeman effect () [ 22 ], i.e. InNiels Bohr brought these facts together in his quantum theory of atomic hydrogen, which opened a new era in spectroscopy and atomic structure.
Bohr extended E. Rutherford's picture of a planetary atom by proposing that the electron, bound by Coulomb attraction to the positively charged point nucleus, moves in discrete circular orbits.

A-The lines in the spectra arise from an electron rising to a higher subshell (that is, the value of l). B-The lines in the spectra arise from changes in an electron's spin. C-The lines in the spectra arise from ionization of the atoms.
D-The lines in the spectra arise from an electron dropping to a lower principal quantum number, n. Quantum mechanics deals with the study of particles at the atomic and subatomic levels. The term was coined by Max Born in Though the theory works to provide accurate predictions of phenomena at the subatomic scales, there is no real understanding of why it works, what it really means or what implications it has for our world picture.
The range of the book has wider benefits. Workers in quantum optics will gain a deeper understanding of the foundations of their subject and field theorists will see concrete examples of open systems, which are beginning to impinge on fundamental theories.

That an atomic system can, and can only, exist per-manently in a certain series of states corresponding to a dis-continuous series of values for its energy, and that conse.The old quantum theory is a collection of results from the years – which predate modern quantum theory was never complete or self-consistent, but was rather a set of heuristic corrections to classical mechanics.
The theory is now understood as the semi-classical approximation to modern quantum mechanics. The main tool of the old quantum theory was the Bohr–Sommerfeld. Physicist James Kakalios, author of The Amazing Story of Quantum Mechanics, wants people to know what quantum physics has done for them lately- .
