Purkinje Phenomenon

Purkinje phenomenon is a phenomenon that was discovered in 1830 by Czech physicist Jan Přikyn. It describes the appearance of bright flashes of light when an electric current passes through rock salt crystals.

The phenomenon was named after Purkinė, who was one of the first researchers of this phenomenon. He noticed that when electricity passes through rock salt crystals, bright flashes of light appear on their surface. These flashes were so bright that Purkine was able to use them to create the first optical telegraph.

Purkinje phenomena were first described in the 19th century, but it was only in the 20th century that a more detailed study of this phenomenon was carried out. The brightness of the flashes was found to depend on many factors, including the temperature of the crystal, the speed of current flow, and the direction of the electric field.

Today, Purkinje phenomena are used in various fields of science and technology, such as optical communications, optical sensors and optical systems. They can also be used to create new types of optical devices that can operate over a wide range of temperatures and voltages.
