Objective: Demonstrate the straight-line propagation of electrons in the absence of any field
Straight-line propagation of electrons in the absence of a field can be demonstrated in a Maltese-cross
tube by showing how the shadow of the electron ...
Objective: Determine the specific charge of an electron
In the fine-beam tube, the path of electrons in a uniform magnetic field can be observed as a clearly delineated ray. This means that the radius of the circular path can be directly ...
Objective: Study the physical principles of the time-resolved display of electrical signals using an oscilloscope
The student oscilloscope can be used to study the physical principles of the time-resolved display of electrical signals on ...
Objective: Demonstrate the superposition of magnetic fields in a vacuum
The absence of interference when magnetic fields are superposed in a vacuum is demonstrated using a
Braun tube. This is done by observing the displacements of the focused ...
