Fluorescencia de resonancia de sodio

Principle

Resonance fluorescence is demonstrated by illuminating a sodium vapour with white visible light. The emitted light is spectrally analyzed and shows the emission spectrum of sodium. Therefore the same atomic levels are involved in both absorption and emission.

Carga elemental y experimento de Millikan

Principle

Charged oil droplets subjected to an electric field and to gravity between the plates of a capacitor are accelerated by application of a voltage. The elementary charge is determined from the velocities in the direction of gravity and in the opposite direction.

Tasks

Constante de Planck y efecto fotoeléctrico (filtros de interferencia)

Principle

A photocell is illuminated with monochromatic light of different wavelengths from a filament lamp with interference filters. The maximum energy of the ejected electrons in the photo-cell depends only on the frequency of the incident light, and is independent of its ...

Constante de Planck y efecto fotoeléctrico (rejilla de dif- ración)

Principle

The photoelectric effect is one key experiment in the development of modern physics. White light from a filament lamp is filtered by a grating spectrometer and illuminates a photocell. The maximum energy of the ejected electrons depends only on the frequency of the incident light, and ...

Efecto Zeeman con electroimán, cámara CMOS y software de análisis

Principle

The "Zeeman effect" is the splitting up of the spectral lines of atoms within a magnetic field. The simplest is the splitting up of one spectral line into three components called the "normal Zeeman effect". In this experiment the normal Zeeman effect as well as the anomalous ...

Experimento de Stern-Gerlach, versión clásica

Principle

A beam of potassium atoms generated in a hot furnace travels along a specific path in a magnetic two-wire field. Because of the magnetic moment of the potassium atoms, the non-homogeneity of the field applies a force at right angles to the direction of their motion. The potassium atoms ...

Resonancia del spín del electrón

Principle

With electron spin resonance (ESR) spectroscopy compounds having unpaired electrons can be studied. The physical background of ESR is similar to that of nuclear magnetic resonance (NMR), but with this technique electron spins are excited instead of spins of atomic nuclei. The ...
