ELECTRON TUBES

Objective: Investigate the deflection of electrons by electric and magnetic fields In a Thomson tube the vertical deflection of a horizontal electron beam can be observed on a fluorescent screen. Such a deflection can be generated by a vertical ... more

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 ... more
