29 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 :
No. of bullets coming to The probability of the bullets
point X in a definite period. striking at a distance X from = 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 open. The results are recorded by the graph in fig. 1C. The results are wonderful. Since both the slits were open, the point of maximum probability where the bullets would strike, was not exactly in front of either slit but it was at the central point of the closed portion between the two slits.
In the second stage of the experiment, slit No. 1 is kept opened while slit No. 2 is kept closed. The results of the experiment are shown graphically by the line P, in flg. 1B.
In the third stage of the experiment slit No. 1 is kept closed while slit No. 2 is kept opened. The results of the experiment are shown graphically by the line P, in fig. 1B.
All the three graphs in figures 13 and 1C, make it very clear that P1, 2 = P + PZ
A smiliar experiment can be performed on waves, created on the surface of water. As shown in fig. No. 2, an object is placed on the surface of water for producing waves. It is then oscillated upwards and downwards with the help of an electric motor. The position of the object produces circular waves on the surface of the water.
On the right hand side at a small distance from the object, there are two slits whose central line is attached to the surface of water.
