The trajectory of a pendulum,as seen from below during a long exposure. The pendulum bob is equipped with a white punctual light source,which emits in all directions. There is a drop in the amplitude,mainly caused by air friction. A filter on the camera was switched from yellow to violet during the exposure. | |
