In summary, the Franck-Hertz experiment was a groundbreaking experiment conducted in 1914 by James Franck and Gustav Hertz that helped to confirm the Bohr model of the atom. By measuring the energy levels of electrons in a neon gas, they were able to demonstrate the quantization of energy and the concept of discrete energy levels. This experiment was crucial in furthering our understanding of atomic structure and paved the way for future developments in quantum mechanics.

Franck Hertz expiriment (maybe you know??)

in experiment i performed of Franck H I got that the maxima interval are becoming larger as the temprature grows.
This is not as it should be by the theore
Can anyone answer that
?

Perhaps a small explanation of the experiment could help generating more repons. I, for one, am not in the mood to search the web for F. Hertz experiments...

I did a google and here's the description. It got the Nobel Prize. Franck-Herz experiment
 

FAQ: Franck Hertz expiriment (maybe you know?)

1. What is the Franck-Hertz experiment?

The Franck-Hertz experiment is a scientific experiment conducted to study the energy levels of atoms and molecules. It was first performed by James Franck and Gustav Hertz in 1914, and it provided significant evidence for the quantum theory of energy levels.

2. How does the Franck-Hertz experiment work?

In the experiment, electrons are accelerated from a cathode to an anode through a gas-filled tube. As the electrons collide with the gas atoms, they transfer energy to them, causing the atoms to become excited. The electrons then continue to the anode, where their energy is measured by a voltage detector. The energy of the electrons is directly related to the distance between the peaks on the detector, which allows for the determination of the energy levels of the gas atoms.

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

The Franck-Hertz experiment was conducted to validate the quantization of energy levels proposed by the quantum theory. It provided evidence that atoms and molecules have discrete energy levels rather than a continuous spectrum of energy.

4. What can the Franck-Hertz experiment tell us about atoms and molecules?

The experiment helps us understand the energy levels and transitions of atoms and molecules. It also helps us determine the ionization energy and excitation energy of atoms and molecules, which are important for various applications in physics, chemistry, and engineering.

5. Can the Franck-Hertz experiment be used to study all gases?

No, the Franck-Hertz experiment is most commonly performed with noble gases, such as neon, argon, and mercury. This is because these gases have well-defined energy levels and are easier to work with in the experimental setup. However, the principles of the experiment can be applied to other gases as well.
