the wavelength was equal to the wavelength in accordance with De-Broglie's formula 1 = h/mv
The question therefore arose : 'Is an electron a wave or a particle ?" In a number of electric phenomena the electron acts in the form of a particle. In a number of experiments we see its emission from the filament of the valve. We can change its path with the help of electric field and magnetic field. Also its path of motion in the cloud chamber can be seen clearly. In the phenomenon of photoelectric effect, the electron itself acts as a particle and it also compels light to act as a particle
Thus it is definitely clear that electrons are particles.
Modern physicists perform three experiments for examining the behaviour of electrons :
1. The experiment with bullets of gun. 2. The experiment with waves of water. 3. The experiment with electrons.
In the first experiment bullets shooting from the gun at various angles pass through slits No. 1. and 2 of the curtain infront of them, as shown in figure No. 1. Slits No. 1 and 2 are so sized that a bullet can easily pass through them and after passing they dash against the wall behind. On this wall there is a detector and the coming bullets are recorded with its help. In this experiment a number of bullets are rapidly shot in quick succession and at enormous speed. It is, therefore, not possible to observe each bullet minutely nor is it possible to notice the hole from which certain bullet passed. On the basis of the principle of probability, we can determine the probability of a certain point on the wall behind at the distance X from the point O. According to the principle of probability
The probability of the bullets No. of bullets coming to point X in striking at a distance X from =
a definite period. the point o
Total No. of bullets coming to the
whole wall in the same period. This experiment is performed in three stages : The experiment begins, when slit No. 1 and 2 are opened. The results are recorded by the graph in
