Description:
Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

Lessons in Optics and Light in the Palm of Your Hand Colorfully illustrate additive and subtractive color mixing, color transmission, absorption and filtering of the different wavelengths of light with this set of primary and secondary color mixing paddles. You can also use the diffraction gratings in this set to view spectra from different light sources. Show students how a spectroscope, colored lights, and even polarized sunglasses work with the contents of this set.
Description:
Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).
