Franck Hertz Experiment with Neon Ministerial Tender Board Equipment, Ministry of Education and Vocational Training Lab Tenders Suppliers India.
Franck-Hertz experiment will demonstrate the validity of the principle of quantization of energy. This experiment was very
important, from a historical point of view, because it supplied
the experimental data for confirming Bohr model ; Bohr was the
first physicist being able to infer the diagram of the electronic
levels of an atom.
This experiment can be carried out with Franck-Hertz tube that
can use mercury or neon. Both these tubes need a specific
power supply and an oscilloscope.
COMPONENTS
Franck-Hertz tube with neon filling and heater
power supply unit
20 MHz DUAL-TRACE OSCILLOSCOPE
TUBO DI FRANCK HERTZ CON NEON
Free electrons collide with neon atoms and generate energy in
quantized packages. During collision, neon atoms are excited
and they persist in this status for short time. Successively,
the neon atoms emit light, due to the energy drop from
intermediate levels to a fundamental state. The emitted light
is included in red-yellow region of spectrum. Light bands will
develop between control and acceleration grids. The parallel
geometry of these grids enables to display these bands on a
window.
Neon-filled tube can operate at ambient temperature.
Electrodes include a cathode, heated indirectly, a control grid,
an acceleration grid and a collector electrode. This tube is
mounted onto a base provided with sockets.
