# Franck-Hertz Experiment,interpretation of graph

• prehisto
In summary, the conversation discusses the presence of multiple maximums in a function, with the first one corresponding to the resonant line of an atom. The individual is unsure why the next maximum is higher than the first and speculates that it could correspond to other energy levels. They also mention that the values of the next maximums are multiples of the first, causing confusion about why they are not equally spaced. They suggest looking at a Franck-Hertz Experiment graphical result for clarification.

## Homework Statement

As it is shown in the attached file,there is multiple maximums of the function.
i understand that the first one (about 4,9V) corresponds to resonant line of the atom.
What I don't understand is why the next one is higher than the first one, what does it mean?

## The Attempt at a Solution

I m speculating,that the next maximums could correspond to other energy levels.
If I m not mistaken,then the values of next maximums is multiples of the first maximum value,so
if the next maximums corresponds to the same energy level,why they are multiples no just continues function with equally placed maximums?

Im sorry if the attachment isn t there.
Then there is some kind of problem.

But any Franck-Hertz Experiment graphical result will do ,to understand the question.

## 1. What is the Franck-Hertz experiment?

The Franck-Hertz experiment is a classic physics experiment performed to demonstrate the quantization of energy levels in atoms. It involves passing an electric current through a tube filled with gas and measuring the energy of electrons as they collide with atoms in the gas.

## 2. How is the Franck-Hertz experiment set up?

The experiment typically involves a vacuum tube filled with a low-pressure gas, an electron source, an accelerating voltage, and a collector electrode. The gas atoms are excited by the acceleration of the electrons, causing them to emit light at specific wavelengths that can be measured.

## 3. What is the purpose of the Franck-Hertz experiment?

The purpose of the experiment is to demonstrate the quantization of energy levels in atoms, which supports the theory of quantum mechanics. It also helps to determine the energy levels of the gas atoms and the energy required to excite them.

## 4. How is the graph in the Franck-Hertz experiment interpreted?

The graph in the experiment shows a series of peaks and valleys, with the peaks representing the energy required to excite the gas atoms. The distance between the peaks is equal to the energy difference between the energy levels in the gas atoms.

## 5. What is the significance of the Franck-Hertz experiment?

The Franck-Hertz experiment played a crucial role in developing the understanding of quantum mechanics and confirming the existence of energy quantization in atoms. It also has practical applications in the development of electronic devices and technology.
