In doing the experiment, it is really important to have an understanding first of the concept to be observed. By taking consideration each factors that may affect the overall effect of Pulfrich Pendulum.
Before the experiment actually started, the person who will do the experiment were briefed for him to be able to do the observation clearly and as accurate as possible…
Then, the pendulum was tested to be actually moving in a way that it is not moving towards you and away from you but it is actually moving side to side. To test this, the experimenter looked at it on the side, (Figure 1, Person B) and viewed the pendulum if it is moving in a straight path and not in circular manner.
Then, when the set up was completed, the person who will do the experiment, (person A) stood 224 cm away from the pendulum set up. Then, final verification of the pendulum was done again to make sure that it is really working.
After that, the real experiment was done. The experimenter (person B) covered the right eye of Person A with the filter and the other eye was remained open while the pendulum was swinging. Then person A was asked to closely observe what will happen on the pendulum set up and to critically look at the object for him not to miss any vital observations that can be done.
Then, person A was asked if he observed the phenomenon that is expected to happen in the experiment. Since the person A had observed the phenomenon, he was asked to describe the said effect in which person A claimed that the pendulum seems following an elliptical path.
After it was verified, the same procedure was repeated, the same procedure applies using the same set of experimental devices and the same person A was asked to do the exper ...
