Jainism : Through Science Behind it there is a detector for detection of waves. It can be moved in the X direction. The detector fully absorbs all the waves falling upon it, and it also measures the intensity of the waves and their amplitude also. This experiment is also performed in three stages :
1. Measuring with a detector, the intensity of waves at different points, while keeping the two slits open, we get the graph of the results as shown in fig. No. 2c.
2. Measuring with a detector, the intensity of waves at different points, while keeping slit No. 1 closed and slit No. 2 open, we get the graph of results as shown by the line I, in the fig. 2B.
3. Measuring with a detector, the intensity of waves at different points, while keeping slit No. 2 closed and slit No. 1 open, we get the graph of results as shown by the line I,, in the fig. 2B.
Graphs of single slits show similar behaviour of particles and waves, while graphs in which the two slits are open, show that the behaviour of particles is different from that of waves.
The intensity of waves I,, is not obtained by addition of the waves I, and I,. It means that the effects obtained from the two slits are not independent of each other. It follows that interference takes place.
The experiment with electrons is as under :
When electrons are emitted from the filament of the heated metal named tungston they behave like real particles. After emission if they are connected with an electric or magnetic field, their direction of movement can be changed. When they are detected by a detector they create pulses in the detector. fig. No. 3 shows when the same electrons pass through slits, like bullets from the gun, they are detected in No. 1, 2, 3, ... etc.
Inspite of all this, it is surprising to observe that experimental results obtained from both slits with reference to eletrons and waves are similar to each other.
The experiment shows that the elctron behaves in the form of a particle, when one slit is open. While it behaves in the form of a
