Franck-Hertz Experiment for Physics Lab - We are offering Franck-Hertz
Experiment useful in Physics and Material Science Lab. This experiment
verifies that:
It is possible to excite atoms by low energy electron bombardment.
The energy transferred from electrons to the atoms always had discrete
values.
The values so obtained for the energy levels were in agreement with
spectroscopic results.
Thus the existence of atomic energy levels put forward by Bohr can be
proved directly. It is a very important experiment and can be performed
in any college or University level laboratory.
The Experiment is consists of the following:
Argon filled tetrode
Filament Power Supply: 3.6-3.4V continuously variable
Power Supply for VG1K: 1.3-5V continuously variable
Power Supply for VG2A: 1.3 - 12V continuously variable
Power Supply for VG2K: 0 - 95V continuously variable
Saw tooth waveform for CRO display Scanning Voltage : 0-80V
Scanning Frequency : 115±20 Hz
Multirange Digital Ammeter Display : 3½ digit, LED
Range : 10-7, 10-8 & 10-9 A
The instrument can, not only lead to a plot of the amplitude spectrum
curve by means of point by point measurement, but also directly display
the amplitude spectrum curve on the oscilloscope screen. This instrument
can thus be used as a classroom experiment as well as for demonstration
to a group of students.
Analysis of Data:
Data obtained for the excitation potential point by point are shown in
Fig. 3. The readings are taken for 1V changes on grid 2 (VG2K). A
significant decrease in electron (collector) current is noticed every
time the potential on grid 2 is increased by approximately 12V, thereby
indicating that energy is transferred from the beam in (bundles)
"quanta" of 12eV only. Indeed, a prominent line in the spectrum of
argon exists at 1048Å corresponding to eV=11.83.
Frank-Hertz Experiment Set-up, Model: consists of the following:
Argon filled tetrode
Filament Power Supply : 2.6-3.4V continuously variable
Power Supply for VG1K : 1.3-5V continuously variable
Power Supply for VG2A : 1.3 - 12V continuously variable
Power Supply for VG2K : 0 - 95V continuously variable
All the power supplies are highly stabilised and output voltages can be
read on 31/2 digit, 7 segment LED DPM with autopolarity and decimal
indication through a selector switch.
