Capítulo 7
La Naturaleza Ondulante de la Luz
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and…
El Espectro Electromagnético
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the…
Interferencia y Difracción
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a…
El Efecto Fotoeléctrico
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency…
El Modelo de Bohr
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei…
Espectro de Emisión
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner…
La Longitud de Onda de De Broglie
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on…
El Principio de Incertidumbre
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined…
El Cuantum - Modelo Mecánico de un Átomo
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave…
Números Cuánticos
It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one…
Orbitales Atómicos
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial…
El Principio de Exclusión de Pauli
The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol…
Las Energías de Los Orbitales Atómicos
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions…
El Principio de Aufbau y la Regla de Hund
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen,…
Configuración Electrónica de los Átomos Multieléctron
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available,…
Caracterización de Emisiones láser infrarrojo lejano y la medición de sus frecuencias
The generation and subsequent measurement of far-infrared radiation has found numerous applications in high-resolution spectroscopy, radio astronomy,…
Rayos x de sincrotrón Microdiffraction y proyección de imagen de fluorescencia de las muestras de rocas y minerales
In this report, we describe a detailed procedure for acquiring and processing x-ray microfluorescence (μXRF), and Laue and powder…
Técnica de medición de temperatura infrarroja para el agua que rodea una esfera magnética pequeño calentado por inducción
A technique to measure the temperature of water and non-turbid aqueous media surrounding an induction-heated small magnetic sphere is presented. This…
