In words, objects and experiments, the exhibition tries to answer many questions about this ubiquitous natural phenomenon, without which there is no life. Throughout history, questions about light have occupied scholars and scientists, philosophers, physicists, mathematicians, etc., and knowledge of light and its properties enables man to use it to his advantage in many areas.

In addition to the theoretical part, in which the authors of the exhibition seek answers to the questions of what light is, what it is like, how it moves and others, a large part is devoted to devices whose operation is connected with light. Among other things, on display are lamps, optical devices and devices that work on the basis of electromagnetic waves, as well as objects that are the result of local knowledge, as many Slovenian companies have been successful in the field of optical technologies in the past and still today.

The interactive part of the exhibition is particularly attractive, where, among other things, reflection and refraction of light will be shown, and visitors will be able to try some physical phenomena and optical devices themselves. Part of the exhibition is dedicated to the blind and partially sighted, who cannot perceive light, and objects and accessories are presented that show how technology makes everyday life easier for the blind.

“What is light? Is it a wave or particles? For two thousand years, scholars have tossed around this question before arriving at an answer that is unusual, namely that light can be either a wave or a stream of particles, depending on how we observe it. This, however, is something that our brains have a hard time understanding and has had very long-term consequences for the development of science and technology. Even quantum physics, which is the basis of all electronics today, is the result of understanding the properties of light,” said the author of the exhibition, Dr. Orest Jarh.
