Sodium Resonance Fluorescence

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.

Planck's "quantum of action" and photoelectric effect(line separation by interference filters)

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 ...

Planck's "quantum of action" and extern photoelectric effec effect (line separation by a diffraction grating)

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 ...

Zeeman effect with a variable magnetic system

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 Zeeman ...

Electron diffraction

Principle

Fast electrons are diffracted from a polycrystalline layer of graphite: interference rings appear on a fluorescent screen. The interplanar spacing in graphite is determined from the diameter of the rings and the accelerating voltage.

Tasks

  1. To measure the diameter of the ...

Magnetic Resonance Imaging (MRI) II



Principle

The aim of these experiments is to show how the spin echo technique can be used to generate 2D MR images of a slice of a well-defined thickness, orientation, and size (Localized Spin Echo 2D). These parameters determine the so-called "field of view" (FOV) of the MR image. ...
