Francs and Hertz's experiments
1. Francs and terahertz experiments were conducted for various atomic collisions. Charge using electrons with atoms of mercury
2.When electrons collide with mercury atoms to generate energy from the electrons to the carbon atom. And atomic energy will be transferred to an electron in an atom to one another.ionization
.Three. Francs of experiments and found Hertz
3.1 if the electron kinetic energy below 4.9 ev (the voltage used to accelerate electrons below 4.9 ev) collisions between electrons and mercury atoms will collide flexible (elastic collision) is equal to ek ek before collision after collision means. Can not change the electron energy levels of the atoms in the ground state has bulbul.Four.9 ev
3.2 when increasing the kinetic energy of the electron is 4.9 ev energy levels of the atoms of mercury ground state (e1) to the excited state (e2) of the first stimulus was
3.3 The increase kinetic energy of the electron to the next. It will stimulate the atoms of mercury atoms II. And three atoms have many more. However, every atom of mercury still want the same kinetic energy 4.9 ev
3.Franc and 5 Hz. Conclusions that In collisions between electrons and atoms absorb energy only numbers. Which indicates that the energy levels of the atom incoherent according to Bohr's theory is 4.9, 6.7, and 10.Figure 4 ev

Experiments of Hertz, and frang
1. Frang and Hz tested concerning the collision of atoms using electron charge to an atom of mercury
2. When electrons collide with atoms of mercury will cause the crates was a charcoal from electron to the atom and atomic energy is to convey to the electrons in the atom. Ionization
3. from the experiments of Hertz, and frang. Find
3.1 If the kinetic energy that an electron is less than 4.9 eV (electron acceleration using the voltage is lower than 4.9 eV) electron collision between Atomic and of mercury would be the indigenous flexible (elastic collision), Ek Ek collision after collision is equal before it shows that the electrons of an atom cannot be made from the Ground State energy level changed passerine Songbird (pycnonotidae). 4.9.
3.2 eV To increase the kinetic energy of the electrons is 4.9 eV, the energy levels of atoms from the Ground State mercury switch (E1) to the first Excited State (E2) of the stimulation is
3.3 If the kinetic energy of the electrons increases. it stimulates the atoms of mercury atoms, the second and third atoms again gradually, but every atom of mercury still wants the same 4.9 eV kinetic energy of
3.4 If the atom of mercury that are triggered in the power level, power levels, E2, and it changes into the Ground State energy level (E1) must release the energy in electromagnetic waves, called a Photon with energy equal to 4.9 eV
3.5 Hz and a trial summary frang in collision between electrons with atoms will absorb some of the energy. That suggests that the energy levels of atoms does not, according to the theory of bo is a 4.9, 6.7, and 10.4 eV as

The trial of Francs and Hz
1. Francs and Hertz have a trial of the collision of atoms, using the electron charge of mercury atoms
2.When electron collision with an atom of mercury will cause the coal and energy from electron to Atom and the atom energy will be transferred to the electron in an atom.
Ionization3. From the experiment and measurement Francs
found that if power 3.1 the electron จลน์ eV lower than 4.9 (Potential difference using the electron acceleration less than 4.9 eV) collision between electron and atom of mercury will be the flexible bumper (elastic collision) is equal to Ek Ek before collision after collision, that electron is not able to make an atom of survival Change power level Ground State.4.9. eV จลน์
3.2 when you add energy to the electron, atom of mercury 4.9 eV Change power level from Ground State (E1) to Excited State (E 2), first of the stimulus.
3.3 if you add energy to the other จลน์ of electron, atom, it will stimulate the second atom of mercury and the third atom. As far as you can go, but every atom of mercury still need power 4.9 eV จลน์ same
3.4 if an atom of mercury that has been stimulated to power level 2 E and energy level will change into energy level Ground State (E 1) will have to unleash the power in electromagnetic waves, called Photon eV have power equal to 4.9
3.5 Francs Hertz and summary of the experiment, in a frontal collision between electron and ATOM will be just some of the specific absorption only, which he pointed out that energy level of an atom is not continued, according to theories of Tabor Ajarn, 6.7, and 10.4 eV as picture
