Document Summary

The quantum-mechanical model explains how electrons exist in atoms and how those electrons determine the chemical and physical properties of elements. Light is electromagnetic radiation, a type of energy embodied in oscillating electric and magnetic fields. An electric field is a region of space where an electrically charged particle experiences a force. A magnetic field is a region of space where a magnetic particle experiences a force. The amplitude of a wave is the vertical height of a crest. The wavelength of the wave is the distance between adjacent crests. Light is also characterized by its frequency, the number of cycles that pass through a stationary point in a given period of time. The electromagnetic spectrum includes all wavelengths of electromagnetic radiation. Waves interact with each other in a way called interference. If two waves of equal amplitude are in phase when they interact, a wave with twice the amplitude results.

LIGHT LAB SPRING 2018 CHEM 1430 Ill. Quantization of Electromagnetic Radiation In 1894, the German physidist, Max Plank, was working for a utility company to maximize visible light output from incandescent lamps using minimum power. Based on theoretical considerations, Planck postulated that electromagnetic energy could only be emitted at discrete values, rather than the continuum of predicted by classical physics, as multiples of the frequency of the radiation. Planck's Postulate took the mathematical form: EÂ·hv where the energy emitted, in Joules, is the product of a constant, h, known as Planck's Constant, and the frequency of the radiation, v. Planck's Postulate was experimentally verified and h found to have the value of 6.626 x 1034 Js(Joule seconds). The idea that electromagnetic radiation energy had specific frequency dependent energy was termed a "quantum of action," a distressing finding for the dlassically trained Planck. Despite his objections, Planck adopted this quantization of energy as a last resort to reconcile experiment with theory. This discovery set the stage for the early understanding of atomic structure, led to the term "photon" to describe the packet of energy carried by light waves, led to an understanding of the photoelectric effect, eventually leading to the development of general quantum theory Planck's Relationship, in combination with the tight equation, c the energy of a photon from frequency or wavelength.

Bohr's Quantum Model for the Hydrogen Atom Ernest Rutherford's Gold Foil Experiment of 1911 demonstrated the nuclear structure of the atom. Questions remained as to how electrons were arranged in the atom. The most common belief called for the negatively charged the late 19h century recognized a particle (an electron) traveling around a body (the positively charged nucleus) would continuously radiate energy, slowing over time, eventually falling into the nucleus. Matter would collapse. Page 8 of 12
