Registratie van elektriciteitsgolven opgewekt door een vonkinductor before 1870

This image, created by Willem Cornelis van Dijk, is a scientific illustration, showing the pattern of electrical waves, or electromagnetic waves, created by a spark inductor, a device that creates electrical discharges, before 1870. The image is part of a larger work, a scientific record of electrical phenomena, a field of study that was in its nascent stage in the 19th century. Van Dijk's work showcases the visual beauty of scientific exploration and the growing understanding of electricity in the early days of its discovery.
